Final-review reviewer flagged two minor staleness items:
- embeds.md §10 ImageEmbed bullets still described the pre-Task-1
shape (no wrapper, no aspect-ratio). Replaced with the actual
current shape, with an explicit pointer to the Dimension
reservation contract section that explains why the dims-null
branch deliberately has no fallback.
- message-list.md said VideoEmbed uses "padding-bottom" without
noting the direct-video branch uses aspectRatio. Now describes
both branches explicitly.
No code changes; both are documentation-only touch-ups.
