What
Render OpenCode symbols and braille spinner frames in V2 simulation PNG screenshots instead of missing-glyph boxes.
Before / After
Before:
ui.screenshot()registered only the Latin subset of Commit Mono. Symbols such as△,✱,⇆, and spinner frame⠹therefore resolved to the canvas renderer's tofu glyph.After: the simulation renderer registers packaged Noto Symbols, Symbols 2, braille, and Math subsets and uses them after Commit Mono in its font stack. Supported UI symbols now render as their actual glyphs.
How
packages/simulation/src/frontend/png.tsregisters Fontsource WOFF2 fallback assets under simulation-owned font families.packages/simulation/package.jsonadds pinned Fontsource dependencies so assets resolve in installed packages and CI.packages/simulation/test/png.test.tscompares each representative symbol's decoded cell pixels against an intentionally unassigned Unicode code point, detecting actual missing-glyph substitution rather than merely checking for non-empty PNG output.Scope
This changes only V2 simulation PNG font fallback. It does not couple simulation to OpenCode Drive and does not change exploration grouping behavior.
