/* Finecolour palette block + single-color page + range archive styles.
 *
 * Type scale strategy:
 *   Kallyas (parent theme) sets html { font-size: 10px } which kills `rem` math
 *   for descendant components. We avoid rem entirely. Each top-level container
 *   pins its own base font-size in px and all descendants use `em` so the whole
 *   block scales as one unit.
 *
 * Container bases:
 *   .fc-color-single   16px (body)
 *   .fc-range-archive  16px (body)
 *   .fc-palette        14px (compact grid)
 *   .fc-related        14px (compact grid)
 *
 * Internal scale (em-of-container):
 *   xs   0.8125em   labels, breadcrumbs, hex chips
 *   sm   0.875em    meta text, code, value labels
 *   md   1em        body
 *   lg   1.125em    subsection emphasis
 *   xl   1.375em    section headings
 *   2xl  2em        page H1
