/* =============================================================================
   teahubery hub — hub.css
   The SIGNED-IN lineage: /login, /change-password and the /hub console. ARB-03
   option A gave this build two design lineages, and this is the second one. The
   public landing keeps the thesis and Tufte look in landing.css; nothing here is
   loaded by / or /privacy, and nothing there is loaded by a Function page.

   THIS IS THE GOVERNED HUB DESIGN SYSTEM, NOT A NEW ONE.
   The component vocabulary is taken, name for name, from the estate's proven hub
   stylesheets so a reader who knows one hub knows this one:
     81-projects/260716-vtas/site/assets/site.css      (tokens, shell, top bar, footer)
     81-projects/260716-vtas/site/assets/auth.css      (card, field, btn, msg, badge)
     81-projects/260716-vtas/site/assets/hub-ui.css    (hub-empty, hub-section, hub-meta)
     81-projects/260624-eastaustralis/site/assets/auth.css
                                                       (tabs, stat, dash-panel, data-table,
                                                        toolbar, form-grid, detail-grid)
   Those hubs split the same vocabulary across site.css + auth.css + hub-ui.css
   because they carry a public marketing site in the same stylesheet family. This
   project does not: its public pages are a separate lineage, so the whole hub
   vocabulary is one self-contained file. That is a packaging difference, not a
   fork of the design system. DO NOT add a second component that does what one of
   the families below already does; extend the family with a modifier instead.

   Four deliberate adaptations to teahubery, each with its reason:
   1. --accent is the teahubery maroon (#800000 / #e0897a dark) already used by
      landing.css and quotes.teahubery.com, so the console reads as part of this
      estate rather than as vtas. No new hue is invented; the ground stays the
      neutral near-white of the governed console, because a dense table needs a
      flat ground and the parchment belongs to the reading surfaces.
   2. --sans is Lato, the estate's UI face, already vendored in /assets/fonts/ and
      declared by fonts.css. One sans family, self-hosted, no external fetch.
   3. --raised / --sunk tokens replace the reference files' per-component dark
      overrides, so every colour is defined once in the token block and the
      explicit data-theme toggle and the system preference both work. The
      reference files put those backgrounds inside a prefers-color-scheme block,
      which an explicit toggle cannot reach.
   4. --warn / --warn-tint are added because the design floor requires an input
      WARNING state and a staleness signal, and the reference files define only
      --ok and --danger.

   Design floor (wrap-rl-website-design.md + Part C of the detail doc):
     - spacing is the 4px scale only (--space-1..8); no ad-hoc pixel gaps
     - five type sizes, largest 24px (--text-xl), which is the dense-console cap
     - grid: the documented auto-fit variant of 12/8/4. .dash-grid at
       minmax(14rem, 1fr) resolves to 4 tracks at 1024px+, 2 at 768px and 1 at
       375px; .form-grid and .dash-cols do the same at their own minimums. A
       parallel 12-column utility would duplicate them, so there is none.
     - every interactive component carries default / hover / active / disabled /
       loading, and every input carries focus / error / warning
     - contrast: --muted 4.8:1, --accent 10.9:1, --ok 5.0:1, --danger 6.5:1,
       --warn 6.3:1 on the light ground, all at or above 4.5:1; the dark values
       are 7:1 or better on the dark ground
     - visible focus ring on everything focusable, never removed without a
       replacement ring on the same element
