/*
 * DESIGN DIRECTION — "Ink & Paper"
 *
 * Warm paper ground, near-black ink, one vermillion accent used sparingly.
 * Square corners everywhere; depth comes from hairline rules and hard offset
 * blocks, never from blur. Display type is Bricolage Grotesque at 800 with
 * negative tracking; reading type is Source Serif 4, self-hosted.
 *
 * Nearly all styling lives in theme.json so the Site Editor can override it.
 * Only rules theme.json cannot express belong in this file.
