/**
 * @taiebs/theme-ui — the eye-safe dual theme.
 *
 * Two palettes, one contract. Neither uses a pure white or pure black surface:
 * the brightest text is #F4F4F6 on #0A0A0C, the darkest ink is #1C1B18 on
 * #F4F3EF. That keeps contrast well above WCAG AA while removing the halation
 * that turns a 12-hour ledger or spreadsheet session into eye strain.
 *
 * The variable names and values below are locked: every component in the
 * workspace reads them, and a value change here is a brand change.
 *
 * Components also pass inline fallbacks (`var(--bg-surface, #121216)`) so a
 * pane still renders correctly during the first paint, before this stylesheet
 * has been applied.
