/**
 * @file One-off codemod: rewrites raw `emerald-*`/`red-*`/`amber-*` Tailwind
 * utilities across client/src to the shared `status-success`/`status-danger`/
 * `status-warning` CSS-variable tokens (see `src/index.css`), so every
 * badge/button/component that means "success"/"danger"/"warning" uses the
 * SAME shade per theme instead of each usage picking its own. The
 * categorical/decorative hue palette (violet, indigo, cyan, teal, sky, rose,
 * pink, orange, yellow, and `blue` — which doubles as both "info" and a
 * categorical role color in places like message bubbles) is deliberately
 * left alone: those distinguish between different *kinds* of thing, not a
 * status, and collapsing them would erase that distinction.
