/*
  THE FAMILY IS GEIST. IT IS NOT IMPORTED HERE, AND THAT IS DELIBERATE.

  SOVERNCOMMAND-COMMAND-VISUAL-SYSTEM-1 settled the family: Geist at the three
  weights the governing boards use (400/500/600), from
  https://fonts.googleapis.com/css2?family=Geist:wght@400;500;600&display=swap
  -- the authority's own line. `--font-heading` and `--font-body` below carry
  it, and they are the only mechanism by which a family reaches any surface, so
  the visual system's choice is in force at every one of them.

  WHAT IS SUPERSEDED, AND NAMED RATHER THAN DELETED: that line arrived here as
  an `@import` at the top of this file, with the note "nocturne.css carries the
  same @import so a consumer of that file alone still gets the family; a
  browser dedupes the two requests". Deduping is true and is not the problem.

  An `@import` of a third-party stylesheet makes THIS file wait on
  fonts.googleapis.com, and a stylesheet that has not finished loading blocks
  the first paint of every document that links it. Measured 2026-09-26 on the
  owner cockpit at 390x844, with that host hung and the whole shell already in
  the service worker's cache: first contentful paint moved from 128ms to
  6068ms. A six-second blank screen on a phone, for a font.

  `display=swap` in the font URL asks for precisely the opposite and cannot
  deliver it from here, because swap governs the font FILE while the stylesheet
  that declares it still blocks.

  A PHONE WITH A WEAK SIGNAL WAS THEREFORE STRICTLY WORSE OFF THAN ONE WITH
  NONE, which is the inverse of what a PWA promises. Measured on the pre-fix
  shell with the worker installed in both cases:

      network GONE                     first paint  44ms
      network present, that host hung  nothing painted at all after 8s

  because a dead network fails the request at once while a half-open connection
  holds the screen for as long as it takes to time out.
  test/integration.cockpit-offline.test.js holds that budget as a rail, so
  restoring the `@import` here turns it red rather than merely reading oddly.

  So each document that uses these tokens links Geist itself, without blocking
  (`media="print"`, promoted on load), and the `system-ui` fallback in
  --font-heading and --font-body is what renders until it arrives -- or instead
  of it, offline, where it never does. A consumer of this file alone still gets
  the declared family and must link the font the same way. Nothing else in the
  served client is cross-origin; keep it that way.

/*
  THEME MODEL — HC-HUMAN-USE-1 additive pass.

  `color-scheme` marks both themes as genuinely supported (form controls,
  scrollbars). Precedence, low to high:
    1. `:root` — the dark values, unchanged from before this pass, so a
       member who never touches theming sees exactly what they always saw.
    2. `@media (prefers-color-scheme: light)` — system preference, when the
       member has not made an explicit in-product choice.
    3. `[data-theme="light"]` / `[data-theme="dark"]` — an explicit member
       choice, set by the theme control and persisted via /api/settings.

  The neutral/accent RAMPS keep their existing step numbers as a RANK, not a
  literal value: low numbers stay "closer to foreground / more prominent",
  high numbers stay "closer to the canvas / more recessed", in both themes.
  That is what lets every existing `var(--color-neutral-N)` call site in
  app.css re-theme correctly without being touched — the ramp was already the
  seam this system needed; this pass gives it a second, independently-tuned
  set of values rather than inverting the first set.
