/* ============================================================
 * core.css — page-level shell + form/component compat layer.
 *
 * Layers on top of:
 *   - /assets/css/design-tokens.css   (base tokens)
 *   - /assets/css/site.css            (homepage components, header/footer)
 *
 * Goals:
 *   1. Map legacy --c-* tokens used by inner pages onto new design tokens
 *      so the inline styles in login/dashboard/poll/etc keep working.
 *   2. Restyle .btn, .card, .alert, .input, .field, .tag, .eyebrow so
 *      every inner page inherits the homepage visual language.
