 * KOL components — foundry (@kolkrabbi/kol-foundry)
 * =============================================================================
 * Component CSS for the type-specimen apparatus. Recreated 2026-07-09 when the
 * type-specimen kit + live-font effects (TypeSample, TypeSpecCard, TextPressure,
 * ColorLoader) moved from @kolkrabbi/kol-component into @kolkrabbi/kol-foundry;
 * their rules moved here from kol-components-atoms.css with them. CSS always
 * lives in kol-theme — the foundry package ships JS only.
 *
 * Layer: this file ships unlayered; kol-theme.css assigns the layer at import —
 *   @import "./kol-components-foundry.css" layer(components);
 * placing it in the `components` cascade layer alongside the rest of KOL chrome,
 * so consumer utilities (a later Tailwind layer) still override it.
 * ============================================================================= */

/* ─── TypeSpecCard — TypeSpecCard.jsx ───

   prose 16px rhythm (Preflight zeroes <p> margin). */

/* ─── TextPressure — TextPressure.jsx ───
   Only the outlined-ghost layer lives here — it needs a ::after pseudo-element
   and -webkit-text-stroke, neither expressible in Tailwind or inline style.
   Everything else (layout, sizing, weight) is Tailwind utilities / inline vars
   on the JSX. Stroke color comes in through the inline `--kol-text-pressure-
   stroke` custom property (defaulted here so the rule is standalone-safe).
   ColorLoader composes TextPressure and needs no rules of its own. */
