-/**
- * migrate-grey-tokens.mjs
- *
- * Replaces all legacy grey hex values and Tailwind grey utility classes throughout
- * src/ with the new 13-shade cool-grey token system documented in
- * artifacts/cool-grey-migration.md.
- *
- * Usage:
- *   node scripts/migrate-grey-tokens.mjs           # Dry run — shows changes, writes nothing
- *   node scripts/migrate-grey-tokens.mjs --apply   # Apply all changes to disk
- *   node scripts/migrate-grey-tokens.mjs --verbose # Also show unchanged files
- *
- * What it changes:
- *   • src/index.css          — injects --cool-grey-* CSS var block into :root if absent
- *   • src/tailwind.css       — injects --color-cool-grey-* @theme entries if absent
- *   • src/ css files           — replaces grey hex values → var(--cool-grey-X)
- *   • src/ tsx/ts/jsx files   — replaces Tailwind gray-N/neutral-N utility classes +
- *                               grey hex values → var(--cool-grey-X)
- *   • src/icons/ svg files    — replaces grey fill/stroke hex → currentColor
- *   • src/ other svg files    — replaces grey fill/stroke hex → var(--cool-grey-X)
- *
- * Alpha variants (#RRGGBBAA) are auto-replaced with color-mix(in srgb, ...) equivalents.

- *                       conversation header → hover the un-truncated model
- *                       badge so the tooltip is visible at the end of the
