/*
 * Findus theme fundament.
 *
 * Everything a component needs (color, spacing, radius) is expressed through
 * the custom properties below. Components must not hardcode hex/rgb values —
 * add or reuse a variable instead. The palette is dark-first: `:root` and
 * `[data-bs-theme="dark"]` hold the active values, `[data-bs-theme="light"]`
 * pre-defines a light set so a future theme switch only has to flip the
 * `data-bs-theme` attribute, no component rewrites.
