marks

Every drawn mark on the glass of First Light: Lucina, as inline SVG. Nothing here imports a texture, so the whole interface ships wherever the world does and renders identically in the browser. Each function takes the colours it should be inked in and returns an SVG string; theme.svg wraps one into a widget node, and theme's mark helpers size it from the live screen.

• lens(brass, brassLit, glass, light, lit) — the lens of Lucina face on: the brass cage, six stepped prism rings and the burner, with lit (0..1) putting first light through the middle of it. The game's mark.
• crystal(core, halo, edge) — a betafite cluster: the octahedron and its two shoulders, in a green-gold halo.
• frisket(brass, brassLit, brassDeep) — a cut brass mask with its bevel and its pin holes.
• pause(color), diamond(color) — the pip's glyph and the focus diamond.
• dawnWindow(dawn, iron, blush, light, sea) — the north window with the sun a fraction of the way up it; the dawn rail's header.
• exposureDiagram(...) — one plate, one crystal darkening the cells around it, one frisket keeping a run of them clear. The picture the whole game turns on; inked twice, once for a dark card and once for the logbook page.
• tube(color) — the speaking tube, beside the Keeper's line.

Every viewBox is authored in a stated ratio and the caller sizes it, so no mark carries a pixel size of its own.
