/* AutoMates: the shared stylesheet every page of the stack layers on.
 *
 * Palette (five colours, everything else derived from them):
 *   black #000000 · Prussian blue #14213d · orange #fca311 ·
 *   alabaster grey #e5e5e5 · white #ffffff
 *
 * Roles. Prussian blue is the voice: text, the navigation rail, a chosen tab
 * or answer. Orange is the pointer: the one action to take next, the mark on
 * whatever is current, progress, focus. Alabaster and white are the surfaces.
 * Orange on white is 2:1, far below what small text needs, so text in the
 * orange family uses --accent, a darkened orange that clears 4.5:1 on every
 * light surface here; pure orange is kept for fills and marks, where the
 * Prussian text on it reads at 7.9:1. Corners are square throughout, badges
 * excepted, and the semantic three (ok, warn, bad) stay outside the palette
 * because Yes and No must never be confused with the brand.
