/* ─────────────────────────────────────────────────────────────
   Notipication — site stylesheet

   This replaces the Tailwind play CDN. That script was ~100KB of
   JavaScript that had to download, parse and generate the whole
   stylesheet before a single styled pixel appeared, from a third-party
   host, on every page load. It is also explicitly not meant for
   production. The visual design is unchanged; only how the CSS arrives
   is different.

   One file, linked by all four pages, so there is a single source of
   truth and no chance of the home page and the legal pages drifting
   apart.

/* ─── font ───
   Self-hosted rather than pulled from fonts.googleapis.com: two fewer
   third-party connections on the critical path, nothing about the
   visitor sent to another domain, and the file is cached under this
   site's own rules. font-display: swap so text is readable in the
   fallback face while the web font loads, instead of invisible. */

/* ─── palette ───
   Light, and indigo rather than green.

   The values are not picked afresh here - they are the APP's own tokens.
   The site, the web app and the Android app are one product, and a
   visitor who taps "Open the app" should not feel the colour change
   under them. --accent is the app's --primary, --accent-soft is its
   --primary-light, --text and --line are its --text and --border.

   Everything below goes through these. The stylesheet used to carry
   about forty hardcoded dark values (#fff headings, #111827 buttons,
   rgba(16,185,129,…) chips, white hairlines) alongside the tokens, and
   that is exactly why the theme could not simply be switched - half the
   page ignored the variables. Now nothing does. */
