feat(01-design-tokens-rams-foundation-03): browser proof page — Rams basemap + signal-orange route placeholder at KL metro
- index.html: MapLibre GL v4 viewer loading ./liberty-rams.json at the KLCC anchor (101.6958, 3.1513, zoom 13); page chrome token-only (var(--color-*) via ../dist/rams.css, self-hosted Geist/Space Grotesk per D-10/D-16) - placeholder route vector: 6px signal-orange polyline + 1px matte-black dashed centerline (mockup route ribbon), color read from the token package at runtime (var(--color-signal-orange)); route layers added LAST (accent lives above grayscale, never inside it); README comment marks the vector as consumed by Phase 5 - basemap:preview script: python3 -m http.server 8123 (cwd=theme serves /basemap/ + /dist/rams.css + /fonts within one docroot — plan's cd-variant was doubly broken; open http://localhost:8123/basemap/) - real-browser render proof (scratch, plan 04 owns committed capture tooling): 8/8 checks pass — maplibre style validation clean, zero failed requests/non-200s, 296 sampled orange route pixels, 0 saturated non-red-hue pixels (grayscale grounding proven pixel-level), 100% warm-gray map area, header chrome rgb(26,26,26)

araharah — Rams basemap browser proof (success criterion 3)
|
||||
------------------------------------------------------------------
|
||||
Renders theme/basemap/liberty-rams.json (the token-derived Rams
|
||||
cartography fork of OpenFreeMap liberty) in MapLibre GL at the KL
|
||||
metro / KLCC anchor, with a PLACEHOLDER route vector in
|
||||
signal-orange.
|
||||
|
||||
ROUTE ACCENT — PHASE 5 CONSUMES THIS VECTOR:
|
||||
The orange polyline below is a placeholder preview of the navigation
|
||||
vector. Per D-08, signal-orange appears in this view ONLY on the
|
||||
route line (raw tolerance) — never in the basemap cartography. The
|
||||
real route layer (Valhalla geometry, guidance state) replaces this
|
||||
placeholder in Phase 5; its color is read from the token package at
|
||||
runtime (var(--color-signal-orange)), not hand-tuned here (D-09).
|
||||
|
||||
OPEN (serve theme/ as docroot so ../dist/rams.css + fonts resolve):
|
||||
npm run basemap:preview --workspace theme
|
||||
→ http://localhost:8123/basemap/
