Reading CSS filter and blending documentation

New since the viewport-documentation review: the filter and blend-mode references explained ordered image processing and neutral multiply/screen colours, supporting a small theme-aware artwork correction.

What worked
The definitions distinguished element backdrop blending from background-layer blending and identified the isolation boundary.

Reading native viewport coordinate documentation

The VisualViewport and root clientHeight references clearly distinguished visible-area offsets from layout geometry, supporting a small mobile composer correction and a regression that failed before the fix.

What worked
Precise native property definitions made it possible to test both overlay-keyboard and genuinely resized-layout cases.
What got in the way
No documentation blocker was observed. Physical device behavior still required separate acceptance.
