/* TatFinder base stylesheet — the fonts, the type/space/radius tokens, base
   element styles and the component classes the app is built from (.btn,
   .card, .tag, .input, .field, .text-muted).

   Forked on 2026-10-11 from the Nocturne design-system export the app used
   to link (apps/studio/_ds/nocturne-569bb669-…/styles.css). The repo owns it
   now: edit it here in shared/assets/, then `npm run sync` (from test/) copies
   it to apps/studio/assets/. Nothing regenerates it, so a future Claude
   Design export cannot change the app by accident.

   What is NOT here: colours and shadows. The palette — the light :root and
   both dark-theme blocks — lives in the <style> block of shared/index.html,
   which loads after this file and is the only place a colour is defined.
   Everything below reads var(--color-*) and themes for free.

   What the fork changed, all without moving a pixel (the before/after
   computed-style and screenshot comparison is in the PR that added it):
   - Inter is vendored (assets/vendor/fonts/) instead of @imported from
     Google Fonts, like Archivo already was, so the app makes no font-CDN
     request and the iOS bundle has its text font offline.
   - Nocturne's purple colour and shadow values are gone; the app overrode
     every one of them.
   - Classes and tokens the app never used are gone: .dialog*, .nav*,
     .table, .seg*, .radio, .card-meta, .elev-md, .elev-lg, .tag-accent-2,
     .hr, .lighten, figure/figcaption, --space-4/6/8, --color-section-ghost.
   - .tag-accent takes the accent fill with --color-on-accent text (see the
     rule for why). */

/* ── Inter ────────────────────────────────────────────────────────────────
   Inter variable (wght axis): Google Fonts' own Inter (v20, 2025-09-10) as
   packaged by @fontsource-variable/inter 5.3.0, split into Google's seven
   subsets with Google's unicode-ranges, so a page downloads only the
   scripts it shows — plain English text loads the 48 KB latin file and
   nothing else.
   The weight range is 400–700 on purpose: that is what the old import asked
   for (wght@400;500;600;700), so a request for 800 still renders at 700 and
   300 at 400, exactly as before. Order matters: where ranges overlap, the
   later face wins, as in Google's own stylesheet. OFL-1.1, licence in
   assets/vendor/fonts/inter-OFL.txt. */
