settlement: hard-delete 14-design Cane Trellis chain (banana-leaf bleed-through)

Steve flagged design 3544 — Gemini image-edit had failed its anti-prompt
('erase every leaf') and the rendered image still contained visible
banana leaves. Audit-traced the entire derivative chain: 13 sibling
Trellis Dream / Clean Trellis / Cane Trellis designs share the same
banana-leaf source image, all generated by gemini-2.5-flash-image-edit
between 2026-05-13 19:14 and 19:20 UTC.

Hard-deleted all 14 (DB row + image file). Files backed up to
~/.wallco-deleted/2026-05-13/ for forensic reference; do not republish
without independent visual review.

Standing rule reinforced: 'No banana leaves. Period.' Prompt-level
anti-prompts to Gemini are not enforceable. Output must be visually
verified.
