/*
 * ============================================================
 * Feralism Component Library — fe-*
 * ============================================================
 *
 * Convention: BEM
 *   .fe-block              block
 *   .fe-block__element     element of a block
 *   .fe-block--modifier    variant of a block or element
 *
 * Consumes design tokens from feralism-base.css and
 * marketplace/design-tokens.css. Defines no variables of its own.
 *
 * Policy:
 *   - Zero JavaScript. Interactivity uses native HTML
 *     (<details>/<summary>, <dialog>, <a>, <button>).
 *   - E-ink optimised: variants differ by SHAPE (border-style,
 *     border-width, weight, geometry) in addition to colour.
 *   - Privacy-first: no external assets, no font URLs, no tracking.
 *
 * This file is the canonical replacement for any Bootstrap-derived
 * vocabulary. New templates use .fe-* exclusively.
