+# F-068 — Implementer evidence
+
+## Scope delivered
+
+F-067 had replaced `aspect-[5/7] max-h-72` with `w-full max-h-72`. The
+container filled the card width but the height was only bounded by
+`max-h`, so all cards ended up roughly the same height as `max-h-72`
+(288 px) regardless of the source image aspect — they looked "flat".
+The product description was still rendered as plain text via
+`{product.description}`, so any HTML markup that the admin now types
+into the WYSIWYG editor (F-064) shows up as literal tags.
+
+## Change
+
+Both defects share one fix: a stable square aspect ratio for the
+listing cards and a `prose` HTML renderer for the description.

++   />
++ )}
+```
+
+The container now enforces `aspect-square` so the card height always
+equals the card width (square cards in the 4-col grid). The image
+keeps `object-contain`, so non-square sources still display without
+distortion — they're letterboxed inside a square.
+
+The description is rendered via `dangerouslySetInnerHTML` so HTML tags
+typed into the WYSIWYG editor (F-062 / F-064) are interpreted on the
+listing cards. `prose prose-xs` adds the small-typography Tailwind
+prose styles (paragraph spacing, list bullets, bold/italic) without
+needing extra CSS.
+
+## Acceptance traceability
+
+| Acceptance criterion | How it is met |
+| -------------------- | ------------- |
+| Each listing card has a 1:1 aspect ratio and the image fits inside without distortion | `aspect-square w-full` enforces a square; `object-contain` keeps the visual inside without cropping. |
+| Product description renders HTML tags on listing cards | `dangerouslySetInnerHTML` on the description; `prose prose-xs` styles the inline HTML. |
+| Existing products without HTML still display | Plain text descriptions render unchanged through `dangerouslySetInnerHTML` (text nodes only). |
+| `verify.sh` is green | Exit 0. |
