 * CASCADE CONTRACT
 * ----------------
 * This file is the single CSS entry point for the site. Its rule order is part
 * of the visual contract: later declarations intentionally resolve earlier
 * baseline declarations. Do not reorder sections merely to group selectors.
 *
 * ARCHITECTURE / CONTENTS
 * -----------------------
 * 1. Historical Material and site baseline (shared primitives and Overview)
 * 2. EdwinOS final component layer (site-hosted fonts, then component owners)
 *
 * Maintenance rule: extend the existing component section in the appropriate
 * cascade layer. Before removing or moving a rule, prove equivalent selector,
 * media context, specificity, importance, and source order.
