The shared "juice" layer, pure-canvas (CSP-safe, no WebGL/shaders), driven off a
clock so both renderers light a scene the same way:
- html/js/render/fxLayer.js (NEW): RK.fx — layered-sine flame flicker, additive
warm glow, a dancing two-layer canvas flame, and pulsing hazard overlays
(lava/poison/spikes) with a footprint-clip callback so it fits square cells
and iso diamonds alike.
- Tavern now has FIRE: 4 corner braziers + a hearth on the left wall throw real
flickering light. Placed along walls, clear of spawn/aisles/tables.
- Both renderers: torch/hearth/hazard tiles draw only their FLOOR base in the
static pass (no more solid amber block), then RK.fx paints the animated flame
/ hazard pulse in the live loop. Tiled caches emitter positions and draws them
over the vignette so light punches through the dark edges; iso adds them as
depth-sorted fx items and keeps its RAF alive while any fire/hazard is onscreen.
- Dungeon hazard zones wired end-to-end in the scene model (lava L / poison P /
spikes ^ chars -> pulsing tiles) — they render the moment the generator emits
them; no client-authoritative fakes.
- fxLayer.js included in tavern.html + match.html.
