/* Rich text editor and rendered rich text.
 *
 * Split out of quaeriva.css so the administration panel can load exactly these
 * rules without inheriting the public theme's shell, which would restyle the
 * whole panel. Both stylesheets link this file; the panel maps the design
 * tokens below onto its own --admin-* palette in quaeriva-admin.css.
 *
 * Tokens used here: --line, --surface, --surface-soft, --ink, --ink-muted,
 * --muted, --teal, --teal-dark, --radius-md, --color-primary,
 * --color-surface-soft, --color-border, --danger.

/* Heading hierarchy.
 *
 * The level has to be readable at a glance, not deduced by holding two
 * headings side by side, so each one carries a colour and a marker of its own
 * as well as a size. That matters most in a long Arabic answer, where a reader
 * skims for the section they want and size alone reads as noise.
 *
 * Only --color-primary, --color-secondary and --color-text are used for text:
 * all three are contrast-gated against light and dark surfaces by
 * tests/Theme/DarkModeContrastRegression.php. --color-accent is decorative
 * here -- bars and dots only -- so it never has to meet a contrast floor.
 *
 * Logical properties throughout, because the same rules render right-to-left.
