REQUIRED:
- _fully_unquote_path range(3) -> range(10) — defense-in-depth so quadruple-
encoded .. is rejected by validator instead of slipping through (not
exploitable but contract violation)
- docs/EXTENSIONS.md trust-model callout moved to top of file with explicit
'don't enable in untrusted env / don't point at user-writable dir' guidance
NICE-TO-HAVE (taken since Nathan asked for all fixes big and small):
- URL list cap at _MAX_URL_LIST=32 to avoid pathological rendering
- One-shot WARNING log for rejected URLs (silent drop now visible to admin)
- One-shot WARNING log for URL list truncation
- MIME map: ttf (font/ttf), otf (font/otf), wasm (application/wasm)
5 regression tests in tests/test_pr1445_opus_followups.py pin all invariants.
