In-chat full plan block:
- TEXT_CAP_SCALE (16.5/12.5): node text renders at text-xs in svg units;
the block now carries maxWidth = extent × cap + mx-auto, so it still
fills the column whenever the column is narrower than the cap, but
never scales node text past the chat prose size (--lh-prose-size).
- GRAPH_PAD (8 svg units) around the full-extent viewBox: centered
strokes (half outside the geometry) and the −4 glow halo were clipping
at the frame edges — the padded origin (-8,-8) keeps all ink visible.
Only the full-extent render pads; the plan window's override viewport
and the popup's fit margins are untouched.
Test pins updated: mx-auto + max-width:232.32px + viewBox='-8 -8 176 152'.
