/* ============================================================
 * app.css — supplemental styles only
 * ------------------------------------------------------------
 * The member-console design system is Bootstrap-first. This file
 * does NOT define a parallel token layer or utility system: it only
 * covers the small set of things Bootstrap 5 does not.
 *
 * Contract:
 *   - Use Bootstrap utilities/components directly in templates.
 *   - Add a rule here only when Bootstrap genuinely cannot express it
 *     (e.g. the HTMX loading-indicator hook, fixed toast positioning,
 *     cross-browser <meter> styling).
 *   - Reference Bootstrap CSS variables (var(--bs-*)) instead of
 *     hardcoded color values so this file stays in sync if Bootstrap's
 *     defaults change.
 *
 * See docs/design-system.md for the full Bootstrap usage guide and the
 * custom-primitives reference.
