/* Shared styling for the comparison and licence pages.
 *
 * The landing (index.html) carries its own ~1200-line inline stylesheet built
 * around one bespoke layout. These pages are plain prose + a table, so they get
 * a small shared sheet instead of a tenth copy of that. Same tokens, same
 * fonts, so they read as the same site.
 *
 * Contrast note carried over from the landing: --sky-600 fails AA at small text
 * sizes on every surface here. Small text uses --sky-ink. Do not swap them.
