/*
 * MCCA design system.
 *
 * The site is the association's public census of Mongolian YouTube. The
 * layout stays calm and spacious so the data reads easily, and the colour comes
 * from the logo: five inks taken from deel robes and painted ger doors, saffron,
 * magenta, coral, turquoise and cobalt, overprinting like risograph ink.
 *
 * Rules the rest of this file follows:
 *   - Each section of the site owns one of the five brand colours (its "hue"),
 *     set on <body data-hue> by renderNav. The masthead band, key figures and
 *     note rules take that hue, so a reader always knows where they are.
 *   - Coloured text uses the darker "-ink" variants, which pass AA on the paper
 *     and on the tints. The bright inks are for shapes, bars and marks only.
 *   - Coral (--gold, kept for the old name) marks the single thing to notice.
 *   - Sentence case everywhere. No all-caps labels, no pills, no arrows.
 *   - Spectral for display and long-form; Golos Text for interface and numbers.
 *
 * TOKEN NAMES ARE THE OLD ONES where other files use them (--panel, --dim,
 * --accent, --gold), so values changed and names did not.
