A ticked checkbox is filled and raised, and a file input is a thumb-sized neo field

daisyUI fills a ticked checkbox only for a colour variant, so without one it drew a tick on nothing: a checkbox without a
colour now takes the primary colour, filled and raised like a button once ticked (an inset well while not), and a
radio's dot is the primary colour. A file input's own button (Choose File, Browse…) is raised like the app's buttons
instead of daisyUI's flat neutral block, and on a touch screen the file input is 44px tall like the other fields; it had
stayed at its small 32px. Mobile/ControlsTests opens Settings' Data import/export on the narrowest phone, which the
sweep (sections closed) never reached, and photographs it in both themes.

+## Testing: end to end against the pasture
+
+`tests/e2e` (Playwright for .NET 1.61.0 on xunit v3) runs the published app in Chromium against SocialPub's pasture: a
+private fediverse of PrivaPub and its peers (GoToSocial, Mastodon, Misskey, Sharkey, Akkoma, Lemmy) seeded with a fake
+community, the town (see `../SocialPub/CLAUDE.md`, "The town"). Never in CI: it needs podman and the pasture.
+
+```sh
+../SocialPub/tools/pasture/run.sh up gts mastodon misskey sharkey akkoma lemmy   # PASTURE_PORT if 6971 is taken
+../SocialPub/tools/pasture/town.sh seed village
+tests/e2e/run.sh [--filter ...]   # publishes with WasmApplicationEnvironmentName=Pasture, serves https://decepub.test, runs
+```
+
+- **The app under test is the deploy's own build** with the environment baked in: Blazor on .NET 10 ignores the
+  `Blazor-Environment` header, so `wwwroot/appsettings.Pasture.json` (API `https://privapub.test`) is chosen at publish
+  time and published only then; the deploy fails if it ever ships.
+- Chromium resolves `*.test` to Caddy on `127.0.0.1:6443` (`--host-resolver-rules`) and ignores the pasture CA. The
+  tests use the Chromium headless shell 1228 cached in `~/.cache/ms-playwright` and never install a browser.
+- **Guards on every test** (`Support/Browser.cs`): the app talks only to its own site and to PrivaPub, a root JWT never
+  goes to `/api` nor a persona token to `/clientapi`, no 5xx, no Blazor error bar.
+- **The tests ask the town** (`Support/Pasture.cs`) which accounts exist and what each object holds (`town.sh expect`),
+  and check the other side of the wire through `town.sh stored`. Each render and action test is also a cell of the
+  town's report (`out/client.jsonl`).
+- Cards carry `data-uri` (their ActivityPub id) and the empty feed `data-feed-empty`, for the tests. The feed renders
+  only the cards near the view, so a test looks for recent cards, and counts what is loaded by `data-feed-count`.
+- **Phones** (`Mobile/`, `Category=Mobile`): `Browser.Open(state, Phone)` opens Playwright's own device presets
+  (shipped in its package): 360×800, iPhone SE (3rd gen), Pixel 7, and the Pixel 7 held sideways, with touch, a coarse
+  pointer and reduced motion; a phone session fails at once if the page doesn't see a touch screen.
+  `SignIn.As(browser, persona, phone)` reuses the desktop sign-in, and any saved sign-in that has expired is renewed.
+  - `RouteSweepTests` measures every page, one screen at a time down its main scroller (`Mobile/fit.js`). It checks:
+    - sideways scroll, unless the strip is marked `data-scroll-x`;
+    - boxes past the screen's sides;
+    - open menus, sheets and dialogs that are cut or outside the screen;
+    - targets without a 44px hit area: hit-tested at their centre and 21px around it, so a crowding neighbour fails
+      them too. Inline links in post text, native media controls and disabled controls are exempt, a fixed floating
+      control covering a target doesn't count, and `data-touch-exempt` exempts one explicitly;
+    - control text under 12px.
+
+    Screenshots, findings and a contact sheet go to `tests/e2e/out/mobile/<run>/`. Cells are `client.mobile.fit.*` and
+    `client.mobile.touch.*`, with the phone as the ref.
+  - `FlowTests` drives the narrowest phone through the menu, a dialog, a new post, a reply, a reaction, a deletion, the
+    full-screen globe, a phone held sideways, a tap into a thread, a picture and the Back button (`client.mobile.flow.*`).
+  - `DesktopUnchangedTests` holds desktop's control sizes.
+- **The globe** (`Render/GlobeTests.cs`): the instruments are built, with the Sun drawn over its subsolar point.
+  - On desktop, a located post written from Milano is pinned, and the globe is photographed in both themes and again
+    turned to the subsolar point.
+  - On a phone, the banner draws little, full screen draws everything with the camera moved back, and closing returns
+    to the banner.
+  - An idle globe draws no frame.
+
+  Photos and stats go to `tests/e2e/out/globe/`.
+- **Restore** (`Category=Restore`, in `Actions/BackupsTests.cs`): a real restore of the pasture from Administration. It
+  ends every session, the town's too, so it runs only when asked (`--filter "Category=Restore"`, never next to other
+  tests) and signs the town in again (`town.sh renew privapub`). Normal runs use `--filter "Category!=Perf&Category!=Restore"`.
+- **Perf** (`Perf/`, `Category=Perf`, left out of the normal runs with `--filter "Category!=Perf"`): `FeedPerfTests`
+  scrolls load0's home (thousands of posts from SocialPub's `load.sh`) to 2000 posts and writes, per step, the time,
+  DOM nodes, JS and .NET heaps and long tasks to `perf.json`.
+- The root project globs `**/*.cs`, so it excludes `tests/**` (`DefaultItemExcludes`), and Tailwind does not scan it.

+## Phones
+
+Below `md` the app is laid out for a phone, and a touch screen gets thumb-sized targets. The rules:
+- **Width and pointer are separate.**
+  - Layout differences between a phone and a desktop use the width variants at the call site (`max-md:`, `md:`).
+  - How big a thing is to a finger uses the pointer: `Styles/touch.css` under `@media (pointer: coarse)`, and
+    `pointer-coarse:` at a call site.
+  - A mouse matches none of it, so desktop keeps daisyUI's sizes (`Mobile/DesktopUnchangedTests` holds them).
+  - A window at most 30rem tall (a phone held sideways) is the `short:` variant.
+- **`touch.css`** is plain CSS in Tailwind's utilities layer, so like `neo.css` it beats daisyUI's sublayers. It sets
+  daisyUI's own size variables:
+  - buttons, tabs, inputs, selects and file inputs are 44px tall;
+  - extra small buttons and the badges that act are 36px, with a transparent `::after` that reaches 44 (5px around
+    the padding box);
+  - checkboxes and radios are 24px, toggles and range thumbs 28;
+  - field text is 16px, so iOS doesn't zoom into a focused field.
+
+  Its `touch-target` utility gives a small link or button a 44px hit area. It can't be used on something that clips
+  its own overflow (a `truncate`d name takes `pointer-coarse:py-3.5` instead), nor on a daisyUI tooltip, which draws
+  its arrow with `::after` (NerdTip takes minimum sizes).
+- **Every target has a 44px hit area on touch,** with 8px between targets in a row (`pointer-coarse:gap-2`). The
+  phone sweep fails anything less.
+- **Overlays on a phone rise from the bottom.**
+  - `DModal Placement="ResponsiveBottom"` is a sheet below md and a centred dialog from md. Every DModal has a visible
+    close button (`ShowClose`, named by `CloseText`).
+  - `DDropdown SheetOnNarrow` turns its content into a bottom sheet.
+  - `Components/PhoneSheet.razor` shows what opens in place on a desktop (the composer, a reply, a quote, an edit) as a
+    sheet on a phone.
+  - All are capped by `dvh`, and the app itself is `h-dvh`.
+- **The Back button closes the newest open overlay** instead of leaving the page.
+  - Overlays register through `IDOverlayHost` (`Components/Daisy`, cascaded from `MainLayout`):
+    - `DModal` and `DDropdown` through the cascade;
+    - the nav menu, `PhoneSheet` and the full-screen globe through `Services/OverlayService.cs`.
+  - `main.js` marks a real Back press (a capture-phase `popstate`), since Blazor can't tell it from the app's own
+    navigation, which closes every overlay and goes on.
+  - No history entries are pushed.
+- **What can't be undone asks first** through `Services/ConfirmService.cs` (`Ask`, shown by `ConfirmHost` in
+  `MainLayout`): deleting a post, taking it off a wall, muting, blocking, leaving a group, dropping a scheduled post and
+  signing out.
+- **On a touch screen:**
+  - a tap on a post opens its thread (`main.js`, `data-thread` on the card, its `data-thread-link`), and cards are
+    pinned to the globe with a mouse only;
+  - a tap on a nerd-stats trigger opens its rows in a sheet (`NerdTip`, `AppStatusService.CanHover`);
+  - pictures open in `Components/MediaViewer.razor`.
+- **The feed on a phone:**
+  - a card's actions are five equal cells (Reply, Boost, Favourite, React, More). Bookmark, the thread and the nerd
+    stats' Details are in More, and the author's picture is in the header;
+  - a new post starts from a floating button;
+  - the globe's banner opens full screen, and a phone held sideways opens it full screen from the tabs;
+  - the feed tabs show their names and fade at the edge where more wait (`edge-fade-x`, `data-scroll-x`).

+  with its own `PublicAct`: joining an event (owner decision 2026-10-05) is asked once more, since the event's server
+  shows who takes part. An event card shows the persona's participation (`privapub.event.participation`: pending,
+  accepted, rejected) with Join or Leave, except for events by invitation or taken on another site (`join_mode`).
+- **What a card shows of other platforms:** custom emoji (`Helpers/CustomEmojis.cs`: a post's or account's `:shortcode:`
+  in its text, name, warning, bio and fields, as the picture the server listed, never inside a tag), a threadiverse
+  post's downvotes next to its favourites, blurhash placeholders until a picture loads (`wwwroot/js/blurhash.js`
+  paints any `[data-blurhash]`: a picture's until it loads, again when its source changes, and for good behind the
+  sensitive-media button), a picture's focal point (`object-position`), and an event's online link, participants and
+  status. A picture, video or sound that fails to load says "Media unavailable" with "Open original"
+  (`data-media-unavailable`), and a gifv plays only on a tap under `prefers-reduced-motion`.
+- **Profiles and search** (`Pages/Profile.razor` at `/account/{id}`, `Pages/Search.razor` at `/search?q=`): a card's
+  author and a notification's account open the profile in the app; "Open original" is the only way to the remote site.
+  A profile shows the posts the account pins above its posts (`pinned=true`: what an account elsewhere features); the
+  persona pins and unpins its own public and unlisted posts from the card's menu.
+  An account that moved says where to (`Account.Moved`, which PrivaPub fills once the new account names the old one),
+  linking the new account's profile.
+  Another's profile and posts can be reported (`Components/ReportDialog.razor`, `/api/v1/reports`): a category, words,
+  and for a remote account a copy to its server, which PrivaPub sends from its own actor, never naming the persona.
+  Who liked or boosted a post opens from its card's menu (`Components/InteractedByDialog.razor`).
+- **Walls** (Smithereen's, FEP-400e): a post written on someone's wall says whose (`privapub.wall`, `data-wall`, linking
+  that profile); one written on the persona's own wall is taken off from the card's menu (`DELETE` on the status, which
+  PrivaPub turns into a `Remove` that Smithereen takes for a deletion). Only the persona's followers may write there.
+  A card in a fixed-height flex column with `overflow-hidden` needs `flex-none`, or it collapses to nothing.
+- **Groups** (`Pages/Groups.razor` at `/groups`): the persona's communities and circles (`GroupService`, `/clientapi/group`):
+  made (a circle unless it is a community, with an invitation code and an optional password), joined by invitation and
+  left; the ones it runs edited, their invitation shown, the requests to join let in or declined, members taken out.
+  Only a group's owner and moderators see who is in it.
+- **Lists** (`Pages/Lists.razor` at `/lists`): made, renamed, given a replies policy and made exclusive (their members
+  leave the home feed) there, filled from the accounts the persona follows; a followed account's profile has a Lists
+  menu too. A list is read as the feed's Lists tab (`FeedFilter.ListId`). Lists never leave PrivaPub.
+- **Filters** (`Pages/Filters.razor` at `/filters`, linked from Settings): PrivaPub marks every status with the filters it
+  matches (`Status.Filtered`), whatever their context; a page tells each card where it is (`Content.FilterIn`: home and
+  lists, notifications, public feeds, threads around the opened post, profiles; none for favourites, bookmarks,
+  conversations and search), and the card leaves the post out (hide), folds it behind the filter's title (warn) or blurs
+  its media (blur).
+- **Articles** fold in a feed (`Content.IsFoldedArticle`): an Article or a Page with its title, or a titled post longer
+  than a few paragraphs (WriteFreely sends Notes with a name), shows its cover, its excerpt and a Read button; the
+  post opened in its thread shows whole.
+- **The composer** (`Components/Composer.razor`) writes a post, a reply (`InReplyTo`), a quote (`Quoting`, offered on a
+  card when the server says the persona may quote it) or an edit of the persona's own post (`Editing`); a post can hold
+  a poll instead of media.
+  - **Media are uploaded as soon as they are picked** (`Services/MediaService.cs`, `Models/UploadMedia.cs`):
+    - each is streamed from the browser's file, and only a 320 px thumbnail (`RequestImageFileAsync`) is kept to show it;
+    - each shows its state (`data-upload-state`: uploading, processing, ready, or failed with Retry);
+    - audio and video PrivaPub answers 202 for are followed (`GET /api/v1/media/:id`, 206 until ready);
+    - the ids are kept, so a post that fails never uploads its media again;
+    - the types and sizes accepted are PrivaPub's own (`/api/v2/instance`, `MediaService.Limits`);
+    - a description changed after the upload is PUT before the post.
+  - **Alt text:** publishing a picture without a description asks once (`data-alt-reminder`, "Publish anyway"), unless
+    the reader turned `PageSettings.RemindAltText` off in Settings → General.
+  - **Edits send the whole post, as Mastodon wants it:** its words and warning from `/source`, its own language and
+    sensitive flag, the media it keeps or adds (`media_ids`; removing them all is `[]`), and the descriptions changed
+    (`media_attributes`). Its visibility and poll stay.
+  - A new post's media are sensitive when the persona's "always mark media as sensitive" (`source.sensitive`) says so.
+  A mention or hashtag being written at the end of the words is offered what PrivaPub already knows
+  (`/api/v2/search`, never resolving), once typing pauses.
+  An edited post's card says so, and its versions open from there (`/statuses/:id/history`, newest first; PrivaPub
+  keeps a remote post's earlier versions from its edits and from Pleroma's `formerRepresentations`).
+- **Threads** (`Pages/ExpandMessage.razor` at `/expand/{id}`): opening a remote thread makes PrivaPub read its replies
+  from their servers (its FEP-7888 `context`, else `replies`), so the page reads the thread again after 4 and 15 seconds
+  and adds what was found, in the thread's order.
+- **Interaction policies** (GoToSocial's, and FEP-5624's `canReply` on a PeerTube video whose comments are moderated): a
+  reply or boost whose target's author must approve it shows so on its card (`privapub.approval`: pending, then nothing
+  once approved, or rejected); one the policy shuts out is refused by PrivaPub (422) and shown as an error.
+- **Settings** (`Pages/Settings.razor`, `Components/Settings/`): the login itself (`AccountEditor`: its password changed,
+  or the whole of it deleted, every persona with it, through `/clientapi/user/update/password` and `/clientapi/user/delete`;
+  the client then signs out), the persona's profile (`ProfileEditor`:
+  `update_credentials` as multipart, its words as written from `Account.Source`, pictures (streamed from the file,
+  and removed with `DELETE /api/v1/profile/avatar|header`), fields, locked, bot,
+  discoverable, indexable and posting defaults; the composer starts a new post at its default visibility), its mutes,
+  blocks and blocked servers (`MutesAndBlocks`), and `DataTransfer`: follows, lists, blocks, mutes, blocked servers
+  and bookmarks exported and imported as the CSV files Mastodon writes, so a persona moves between servers. An import
+  resolves each row through PrivaPub and acts one row at a time; it can be stopped. Above it, `PersonaArchivePanel`
+  (`ArchiveService`, `/clientapi/persona/{id}/archive`; owner decision 2026-10-07): the persona's whole archive made on
+  PrivaPub in Mastodon's layout and downloaded through a link; and an archive (its own, or Mastodon's) uploaded in pieces
+  by `js/transfer.js` and imported into it, the parts chosen (likes, located and scheduled posts off unless ticked),
+  with progress, a report and Stop. Imported posts are delivered to no one.
+- **Administration** (`Pages/Administration.razor`, `Components/Admin/`, for moderators): reports, then for
+  administrators the servers blocked for everyone, the federation statistics and the backups. PrivaPub has no admin list
+  of users, and adding an admin endpoint waits for the owner, so the Users section stays empty.
+- **Backups** (`Components/Admin/BackupsPanel.razor`, `/clientapi/admin/backups`; owner decision 2026-10-07): the server's
+  backups (nightly, before each deploy, made here, uploaded), with what runs and the last restore's report.
+  - A download asks for the password and gives a link good for ten minutes, a plain anchor, so the browser saves the tar
+    to disk.
+  - An upload never passes through .NET's memory: `wwwroot/js/transfer.js` PUTs `file.slice` pieces at the offset PrivaPub
+    has, and carries on from what PrivaPub says after a refused or lost piece.
+  - A restore asks for the password and the server's host typed out, and says what it means. PrivaPub stops, restores as
