 *   neutralizes `//` comments). On a parse failure the block is dropped (no raw
 *   fallback — a raw scss scan is exactly the false-positive source we avoid).
 * - no `lang` / `css` / `postcss` → passed through verbatim.
 * - anything else we can't safely treat as CSS (`sass` indented syntax, `less`,
 *   `stylus`) → dropped, mirroring how `.sass` files are skipped.
