   btools.ai — design system
   Ported from the shipped BidBrief web app (web 2.2.0) per
   BIDBRIEF_DESIGN_SYSTEM_HANDOFF.md, Option B: keep the brass/gold brand and
   adopt BidBrief's *structure* (atmosphere → scrims → glass → motion). The
   parent brand stays the neutral, premium frame; BidBrief blue reads as a
   product inside it. An ice-blue site was tried on 2026-08-11 and rejected —
   gold is the client's settled preference. Do not re-theme without asking.

   Zero dependencies. No framework, no CDN, no build step, no external requests
   at all — the fonts are self-hosted (see section 0).
   ========================================================================== */

/* --------------------------------------------------------------------------
   0. FONTS — self-hosted, deliberately.
   These were originally pulled from Fontshare's API at runtime. That was
   dropped after the API returned a "temporarily restricted" stub instead of
   the stylesheet during testing, which silently fell the whole site back to
   system fonts with no error anywhere. A brand's typography should not be a
   third party's uptime problem. Self-hosting also removes a DNS lookup + two
   round-trips, and lets the CSP drop its font-src exception entirely.

   Clash Display and Satoshi are by the Indian Type Foundry, released free for
   personal and commercial use under the ITF Free Font License, which permits
   self-hosting. Files: assets/fonts/*.woff2 (107 KB total, all five weights).

   Two animations, listed in order, on one element:

   1. `hub-arrive` — the entrance. Slow (3.8s) and widely staggered (0.8s apart)
      so each row resolves out of blur on its own beat instead of the group
      snapping in. Ends with `forwards` fill holding the settled state.
   2. `hub-float`  — the idle. Starts only after that row has arrived, then
      drifts it a few pixels and breathes its opacity forever.

   Both animate `translate` (never `transform`), leaving the `scale` property
   free for the hover rule above — so a row can drift and expand at once.
   `hub-float` keeps the default `fill-mode: none`: with `both` it would
   back-fill during its delay and stomp the entrance before it ever played.
   Per-row float durations are deliberately mismatched (7.4/8.6/9.3/8.1/7.9s)
