/* =============================================================
 * Luci Finance — components.css
 * Shared, opt-in component classes for the Luci Finance platform.
 *
 * CONVENTION: every class here is prefixed "lf-" (Luci Finance).
 * Linking this stylesheet changes NOTHING on an existing page until
 * markup opts in by using an lf-* class. There are no element/tag
 * selectors and no bare utility names — the prefix is the namespace.
 *
 * THEMING: all colours, radii, shadows and fonts come from the shared
 * design tokens in lucidity-theme.css via var(--…). There are NO raw
 * hex colours in this file (rgba() with the theme's neutrals is used
 * only for translucent scrims/overlays).
