/*
 * Volare dashboard — foundation.
 *
 * Three systems live here and nothing overrides them elsewhere:
 *   1. Type. Ten sizes (--text-2xs … --text-5xl) and one role class per role
 *      (.t-*). No file in this app sets a font-size that is not one of those
 *      tokens; 12px is a hard floor for lowercase text and there is no
 *      viewport scaling of any kind.
 *   2. Surface. Every component surface is a solid colour. Translucency is
 *      reserved for the decorative artwork (.atmos-*, hero-art.svg,
 *      side-art.svg, sparkline fills) and for modal scrims, which cannot do
 *      their job opaque.
 *   3. Spacing. One 4px grid (--s1 … --s8) and one value per relationship:
 *      card padding, card gap, row gap, section rhythm, list row height.
