{# ── Build the filtered field set ──────────────────────────────────────
Strategy:
1. Find all grid rows that contain at least one rated rating field.
2. Collect every field whose grid row overlaps a rated row.
3. Also collect section fields that immediately precede a rated group.
4. Re-number rows sequentially (1-based) so there are no gaps.
