/*
 * miaword.com — tokens and primitives.
 *
 * Every value here is transcribed from src/theme/tokens.ts and the HTML
 * references in docs/, so the site and the app cannot drift apart. Where the
 * two disagreed, docs/odeme.html won: it is the newest surface in the repo
 * and the app is being brought to it, not the other way round.
 *
 * The four rules the app is built on, from tokens.ts, hold here too:
 *   1. Every interactive surface is a solid block with a darker edge under it.
 *   2. Static surfaces use a border, not a shadow.
 *   3. Corners are generously rounded. 16 is the default, never under 12.
 *   4. Type is heavy. 700 is the lightest weight that ever appears.
