/*
 * ChainhoistDB — the one stylesheet.
 *
 * Order: tokens → Bootstrap 5.3 mapping → base → shell (header, footer,
 * bottom nav) → shared components → page sections → admin.
 *
 * Rules of the house:
 *   - Colours, type, spacing, radius and elevation come from the tokens
 *     below. No raw hex outside the token blocks.
 *   - Dark is the default (<html data-bs-theme="dark">). Light lives under
 *     [data-bs-theme="light"]. The header toggle persists the choice.
 *   - Flat surfaces, 1px hairlines. Cards change border colour and lift
 *     2px on hover. No gradients, no drop shadows on cards, no blur.
 *   - Motion is progressive and brief (section 10): view transitions,
 *     one-time reveals, count-ups. All off under prefers-reduced-motion.
 *   - Dense and scannable: this is a reference tool for riggers. Numbers in
 *     tables are tabular.
