The app's own pages in the server's nine languages

scripts/gen-i18n.py writes ui/i18n.js from the server's catalogues where the
same sentence exists and from its own table otherwise; the pages pick the
language from the browser and fall back to English.

 ## [Unreleased]
 
+### Changed
+
+- The app's own pages take their look from the server's `tokens.css`, copied by
+  `scripts/fetch-tokens.sh` from a server tag and pinned in `tokens.lock.json` (the script with
+  no argument verifies the copy). The hand copy had drifted: `--danger`, `--control-h` and
+  `--text-xl` were not the server's. The pages name no colour, size or space of their own, and
+  no font is bundled: the font rules are left out of the copy, so the title bar and the
+  first-run page are set in the system's monospace face.
+- The window's frame is painted in the theme's border colour read out of `tokens.css` at build
+  time (`build.rs`), not a value written in Rust, and it changes with the theme.
+- The first-run page and the title bar speak the system's language when it is one of the
+  server's nine (Czech, German, Spanish, French, Hungarian, Italian, Polish, Slovak; English
+  otherwise). `ui/i18n.js` is generated by `scripts/gen-i18n.py`: the sentences the server also
+  has are translated as the server translates them, the app's own are in the script.
+
+### Fixed
+
+- The title bar followed the desktop's light or dark setting, not the account's theme, so it
+  could be dark over the parchment (Shire) page. It now follows the server page: a script in the
+  content view reports the page's theme to the app, which paints the frame, the title bar and
+  the first-run page in it and remembers it for the next start. The server's pages still get no
+  IPC; the report is a navigation attempt the app reads and refuses.
+- The close button's hover colour was a literal white; it is the theme's inverse ink.
