* perf(marketplace): browser-cache cover photos + restore Curated tab filter spacing
Cover photos on /marketplace grid now serve with `Cache-Control: public,
max-age=2592000, immutable` plus URL fingerprinting (`?v=<commit-sha8>`
for curated, `?v=<version_no>` for flea) so browser refresh stops hitting
the server entirely for unchanged assets. Per-plugin RBAC dropped from
the three image endpoints (curated_asset, curated_mirrored, get_entity_photo)
in favor of login-only auth — eliminates _system_db_lock contention on
parallel image requests. Per-request magic-bytes revalidation also dropped
from curated_asset (it was re-reading the file just to discard the bytes,
then FileResponse read it again).
Spacing bug: sort-dropdown commit (6be1cee) wrapped .mp-filter-row in a
new flex container with inline margin-bottom:4px, masking the original
12px CSS rule. Curated tab (where .mp-type-row is hidden) ended up with
4px between filters and the card grid. Wrapper margin restored to 12px.
See CHANGELOG entry under [Unreleased] — the RBAC relaxation is called
out under ### Security with explicit threat-model rationale for AI/human
reviewers.
* test(marketplace): update renamed-html-as-png test for dropped magic-bytes check
Magic-bytes body validation was dropped from `curated_asset` in the previous
commit — the request path now relies on extension allowlist + pinned
Content-Type + nosniff + strict CSP to neuter mismatched payloads at the
browser layer. Update the test to assert the new defense-in-depth posture
(200 served, but Content-Type=image/png + nosniff + CSP=default-src 'none')
rather than the gone 415.
