/**
 * Validate that module ListView.svelte files use theme tokens instead of
 * raw white-alpha Tailwind utilities.
 *
 * Background: the unified Mana app supports multiple theme variants (Lume,
 * Nature, Stone, Ocean, plus dark). Utilities like `text-white/80`,
 * `bg-white/5`, `border-white/10` ignore the active theme and can render
 * white-on-white in light variants. The theme tokens (`text-foreground`,
 * `bg-muted`, `border-border`, etc.) are the canonical replacements —
 * they're generated by Tailwind v4 from `packages/shared-tailwind/src/themes.css`
 * and resolve per-theme automatically.
 *
 * Rule: `src/lib/modules/**\/ListView.svelte` must not contain
 *   - `bg-white/` (e.g. bg-white/5, bg-white/10, hover:bg-white/5)
 *   - `text-white/` (e.g. text-white/80, hover:text-white/90)
 *   - `border-white/` (e.g. border-white/10, focus:border-white/20)
 *
 * Suggested replacements:
 *   bg-white/N       → bg-muted/N or bg-card
 *   text-white       → text-foreground
 *   text-white/40-60 → text-muted-foreground
 *   border-white/N   → border-border
 *
 * `text-white` without an opacity modifier is allowed when it sits on a
 * guaranteed-dark surface (mood gradient overlays, photo viewer) — those
 * are brand literals per the themes.css policy.
 *
 * Zero deps — runs as plain Node ESM. Uses `git ls-files` to respect
 * .gitignore.
