/* ---------- Typography ----------
   The Google Fonts @import that used to live here was removed (§9.10 / §4.2).
   It sent every user's IP address to a third party on every page load, it
   blocked first render behind a cross-origin request, and it made the app fail
   in an air-gapped shop — which is a realistic deployment for a machine shop.

   The stack below resolves entirely on-device. The brand typeface (Geist, as
   used on the main site) will be self-hosted as part of the UI revamp; see
   BRAND.md. Nothing here reaches the network. */

/*
 * `.form-section` is a <fieldset>, and carried no rule of its own — so every
 * long form drew the user agent's default `2px groove` box in a colour no
 * stylesheet chose (#efefef light, #6b6b6b dark). It ignored the theme, it was
 * the only border on the site not taken from a token, and nested inside the
 * form card it read as a stray outline around the inputs.
 *
 * The grouping is still real and still worth keeping — it is what makes the
 * <legend> mean something to a screen reader — so the box goes and the legend
 * becomes a visible heading instead. `min-width: 0` is not optional: a fieldset
 * defaults to `min-width: min-content`, which stops it shrinking inside a flex
 * or grid parent and lets wide fields push the form wider than the viewport.

  Staggered child animations — deliberately no longer staggered.

  Each child started at `opacity: 0` and faded in over 400ms behind a delay of
  up to 300ms, re-running on every route change and every remote write. The
  effect was a wave of half-visible cards for the best part of a second: a
  screenshot of the dashboard routinely caught two KPI tiles washed out and a
  third missing, which is what it looked like to use as well.

  Two things were wrong with it. The visible one is that it made a static page
  feel like it was still loading. The dangerous one is that `opacity: 0` was
  the *initial* state, so any child past the sixth — or any child whose
  animation was interrupted by a re-render mid-flight — stayed invisible with
  no way back.

  One short fade on the container replaces it. Content is never invisible
  waiting for an animation that may not arrive.
*/
/*
  No entrance animation on the children at all. The first attempt at fixing
  this kept a short fade with `animation-fill-mode: both` — which still applies
  the `from { opacity: 0 }` keyframe *before* the animation starts, so the
  tiles were still transparent at the moment they were rendered. Any fade whose
  start state is invisible has the same hazard; the only version that cannot
  strand content is not having one.

  The container still fades (`.animate-fade-in` on #content), which is enough
  to soften a route change without any individual card being able to get stuck.
