/* Nursing Ready — compatibility layer.
 *
 * The migrated guides, calculators and legal pages carry Tailwind utility
 * classes inline from the v1 site. Rather than rewrite ~28 pages of markup
 * by hand, this file implements exactly the utilities those pages use and
 * RE-TOKENIZES the colour ones onto the warm-clinical palette — so
 * `text-teal-600` renders pine, `bg-white` renders warm surface, and
 * `bg-gray-900` renders warm ink. No Tailwind CDN, no build step.
 *
 * Inventory generated by scripts/site_v2/extract_classes.py (198 classes,
 * minus the nav/footer/hero ones whose markup is replaced wholesale).
 * Loaded LAST so an explicit utility can still win over .prose defaults.
