Posts share the section bundle

Posts sit loose in the section bundle, not their own.

content/post/cryengine, garden, general, linux and programming held 47 page files as plain .md files next to the section’s _index.md. Hugo resolves the page resources of a loose page file to every file in its folder, so each of the 47 read the section’s featured.webp and its siblings as its own resources. The functional specification says each post is a page bundle holding its own media: true of the 99 posts written as bundles, false of these 47.

Each of the 47 files is moved with git mv to content/post/<section>/<name>/index.md, so every post under content/post/ is a page bundle of its own: 15 cryengine, 15 garden, 7 general, 6 linux, 4 programming.
No file content is edited: the change is 47 renames with 0 insertions and 0 deletions.
Kanban cards keep their flat files. The filename is the card id, which the documentation shortcodes match, which kan writes, and which pnpm run test:kanban validates: giving a card a folder of its own breaks all three.

Acceptance Criteria

find content/post -name '*.md' ! -name '_index.md' ! -name 'index.md' prints nothing: 0 loose post files, 47 before.
Each of the five section folders holds _index.md, its featured.webp, and folders only.
pnpm run test passes: 657 pages, 408 processed images, 407 pages with exactly one h1, 33 cards valid.
The build writes the same 1157 files as the build before the change, so every URL survives, /post/general/first-steps-with-fpga/ included.

Notes

Hugo’s title-case cache is an LRU shared across its string transformations, so the number of titles computed in a build decides how the deep-fried term title renders. A control build of HEAD with one unrelated page added flips it between Deep Fried and Deep-Fried across 4 tag pages, which is what the 4-file diff of this change shows. Nothing in the move caused it.
Found while removing the inherited featured image, in p2-us-featured-images and p2-is-card-image-parent-fallback: the loose files are why a post page’s own resources held the section’s featured.webp at all.

Not in scope

A carousel over the images a post bundles: p2-ft-post-image-carousel, which now reads a bundle that is the post’s own.
