Subject: [PATCH] test(hdr-regression): tighten Window C maxFrameFailures
 budget after Chunk 1 fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Window C (direct <video> opacity tween) was previously listed as a known
failure with a maxFrameFailures budget of 30 to absorb expected drift
until Chunk 1 (opacity pipeline bugs) landed.

After the Chunk 1 fix, the regression test passes against the existing
golden with 0 failed frames, confirming Window C now renders correctly.
Regenerating the golden produces byte-identical output (HEVC encoding
is deterministic and the opacity fix doesn't perturb pixels at the
PSNR ≥ 28 checkpoint threshold).

Tighten maxFrameFailures from 30 → 5 to leave only a small budget for
encoder noise. Window F (transform + border-radius) remains pending
Chunk 4; its broken state is currently baked into the golden, so the
suite is green and Chunk 4's regen will catch any drift.

Update README.md to reflect Window C is fixed and the tightened budget.
