/*
 * CoinPub theme — ported verbatim from the Lovable export's src/styles.css
 * (design tokens + @utility classes). Values, class names, and selectors
 * are unchanged. Only the delivery mechanism differs: the Lovable project
 * used Tailwind's build-time @theme/@utility directives; this file provides
 * the same resulting CSS as plain rules so it works via a stylesheet link
 * in a Hugo site with no Node/Tailwind build step. Tailwind's utility
 * classes themselves (grid, flex, px-4, etc.) are loaded separately via the
 * Play CDN in baseof.html — see the flag in the write-up about swapping
 * that for a compiled Tailwind build later.
