The first header value started at the authored slot edge, which now sits on the
parchment band's corner bracket, so the title overlapped the trim. Header
labels are clamped to the band face (edge fraction plus a small pad) in both
locales. The header settings control was still a flat angular utility plate;
it now uses a compact member of the same hand-drawn plate family with the
engine-rendered settings glyph, so the top row carries no vector chrome.
Information surfaces were still flat drawn chrome while the commands were
already painted, so the page mixed two material languages. The warning rows,
status card, summary card and header now use a hand-drawn parchment panel, the
command dock is a painted wooden rail, and the warning severity marks use
enamel badges. All four use the same fraction-based nine-patch as the command
plates and import with mipmaps so the wide aspect ratios stay clean at 760.
The warning stack also carried no severity in its data, so all three rows fell
back to one colour; the visual fixture now matches the production
["warning","notice","info"] facts and the view falls back to that sequence
by row order instead of a single default.
Add runtime/ui/shared/asset_chrome.gd: large parchment/wood surfaces use the
approved generated components with ornament-safe asymmetric nine-patch
margins, while small controls use the size-independent market_chrome vector
material so decorative pixels are never stretched into bands. Record the rule
in M52_SHARED_UI_RULES.md before another page reuses it.
