/* Tabulated — base stylesheet.
 * Theme tokens live HERE and only here: one light block (:root) and one dark
 * @media block. Any token added to one MUST be added to the other (house rule);
 * mirror changes into docs/style-guide.md in the same commit.
 *
 * The palette is exactly three colors (docs/design/iOS.png is the source
 * comp): paper, ink, and red. Dark mode is a strict paper<->ink swap done via
 * the --bg/--fg pair; --red never changes. Everything on a red surface derives
 * from the same pair: structural text (wordmark, icons, labels) uses --bg,
 * data values use --fg, buttons are --fg fills with --bg text. */
