- Pure synchronous helper returning minutes (>= 1) from either a pre-computed
word count (number) or raw text (string, tokenized on whitespace).
- Client-side safety net when `article.minutes` isn't yet populated
(e.g., dev hot-reload before the Nitro hook re-parsed). Source of truth
remains the Nitro `content:file:afterParse` hook (D-19).
- Same 200 wpm formula as server-side hook — ensures listing ↔ article parity.
- Auto-imported by Nuxt thanks to `use*` naming convention.
