Cards fall back to the section image

A card with no image of its own shows the section’s image.

be-best/layouts/_partials/images/featured-image.html:14 falls back to .Parent.Page.Resources when the page has no featured.webp. In a listing, every image-less post therefore renders its section’s image, and the same large file repeats across the page. All 6 cards on public/post/garden/index.html render /post/garden/featured_hu_ecf1cdc248bd6b78.jpg: no garden post in that page carries its own featured.webp. At the 1920w variant the section image weighs 363 KB, so the page requests 2.2 MB of one picture.

Cards fall back to the section image

• A card selects an image from its own page resources only: the .Parent.Page.Resources lookup is off the card path, behind an inherit flag a card does not set.
• A card with no image renders text only, with no <img>, no <picture> and no bigImgDiv wrapper: the lookup returns nil and the card writes nothing, not even the empty link that used to wrap the image.
• The page-level featured image keeps its inherited-image behaviour, documented as intended for post pages: the flag defaults to true, and featured-image.html documents both paths.

Acceptance Criteria

• On public/post/garden/index.html, each image URL appears at most once, and the number of card images equals the number of cards whose post owns a featured.webp, 0 on that page today. 12 cards, 0 images.
• public/post/index.html keeps 6 cards with 6 distinct image URLs. 6 cards (the section holds 6), 6 distinct URLs, each a section’s own image.
• No page in public/ repeats the same featured image URL in two cards: 0 pages repeat one.
• pnpm run test passes.

Notes

• Fixed with the card redesign of p2-ft-card-design-improvements, which owns the card path. The lookup is partial "images/featured.html"; featured-image.html keeps the page-hero path with inherit defaulting to true, and the card partials pass inherit false.
• The criteria counted 6 cards per listing. Section listings paginate at twelve entries, as the functional specification has always said, and the card redesign moved the four paginated sections from 6 to 12 to match, so the listings named above are measured at 12.
