/* ── Statistics: shared UI components of the detail layer ─────────────────────
   Ported 1:1 from the approved mockups (`design/mockups/Stats*Tap*.dc.html`,
   `Stats*All*.dc.html`, `Stats*Card*.dc.html`); the generator is `reference/lib.mjs`. Each rule
   below has an inline `style=` twin in one of those files — when in doubt, the mockup decides.
   Only the class names changed (prefix `stats-ui-`), plus a handful of `--ui-*` tokens.

   The components are mounted outside `#view-stats` on some screens (a card can be lifted into a
   panel), so the tokens are declared on the component roots as well as on the view. Corner radii
   stay ≤ 6 px; touch targets are 44 px on a phone and 36 px from the desktop breakpoint, as the
   spec asks. */

/* The mockups' colour constants `C.*` that have no app token: card/track/unknown/chip already
   exist as `--stats-*` in `css/stats.css`; the two float values are new and live here. The block
   names every component root, because a component can be mounted on its own (a standalone search
   box, a card lifted out of its panel), and the tokens must travel with it. */

/* ── Tones ──────────────────────────────────────────────────────────────────────
   Shared by bars, cells, segments, meters and swatches. Values are the mockups' colours mapped to
   the tokens the app already defines: the mockups' slate grey is `--stats-unknown`, their amber is
   `--warn`, their sky blue is `--accent`. (The amber and sky hex values stay in the token blocks;
   a theme test bans them anywhere else.)

   This block stays LAST in the file, on purpose. A tone is one class (specificity 0,1,0), and so are
   the default fill `.stats-ui-hour-fill` and the cell track `.stats-ui-cell`. Declared after them, a
   tone wins at equal specificity. Declared before, the default fill silently repainted every bar
   orange. Rules that need to beat a tone have a higher specificity (`.stats-ui-hour--missing
   .stats-ui-hour-fill`), so they still do. */
