Re-express showcase as frameTarget: 'self' consuming frame, with deprecated aliases for its old attributes (breakout bleed retained), and document the surface model.

showcase is frameTarget: 'self' consuming frame; old shadow|bleed|offset|aspect|place are deprecated aliases (warn) per the migration table; breakout retained.width concern (article named-line grid) distinct from displace/host-owned-clip; showcase/figure is the attribute-surface wrapper.elevation=self, frame=media) and the preset registry.@refrakt-md/runes + @refrakt-md/lumina.packages/runes/src/tags/showcase.ts, Showcase config, showcase.css.

Branch: claude/spec-086-surface-chrome
Showcase is frameTarget: 'self' (config.ts); its shadow/bleed/offset/aspect/place attributes are deprecated aliases mapped to frame-* facets in showcase.ts (shadow soft/hard/elevated → sm/md/lg), each warning once; breakout retained via the host-owned-clip CSS. Old showcase modifiers/styles/postTransform removed; showcase.css trimmed to structural + breakout.site/content/extend/theme-authoring/surface-chrome.md (the elevation/frame surface model, frames registry, frameTarget, host-owned clip, full-bleed-is-width, showcase migration table) + config-api.md frames/frameTarget entries..changeset/spec-086-surface-chrome.md (runes/transform/lumina/types minor).site/content/runes/{card,figure,showcase,bento}.md) were not individually rewritten; the surface model + preset registry are documented on the theme-authoring page. A per-rune reference pass is a reasonable follow-up.
