v0.2.0

Added

• Irregular room shapes: cell-union structure footprints (building : K5..M8 K9..K12) now render with a fully derived perimeter — L-shapes, notches, and reentrant corners get correct walls, light, coincident-wall and opening semantics, UVTT line_of_sight, and room labels that stay inside the bent room. ruined side words select perimeter edges by facing. The manor's kitchen gained a scullery corner to show it off.
• UVTT export (exportUvtt / exportUvttSource in @chartdown/render-svg): battlemaps export to Universal VTT one file per level — walls minus opening edges → line_of_sight, openings → portals (closed per the passes facet; a window is a los hole plus a shut portal), light= → lights, grid → resolution. Geometry shared with the light engine so export can never disagree with the render; the caller supplies the raster image (ADR 0010). Player-mode exports carry no secrets.
• Obsidian plugin (in-repo at packages/obsidian; community-store submission pending): chartdown fences render in place with a per-map toolbar — GM/player toggle, SVG export, UVTT export with the image rasterized in-app. Exports land next to the note, name their path, and reveal in the system file explorer.

Changed

• Spec 06 §9 (UVTT export) is now normative, upgraded from the original non-normative mapping note.
