New js/layers/fires.js — fetches EONET open wildfire events directly (ACAO:*),
refreshes every 15 min, rebuilt wholesale (no time dynamics — EONET events are
slow-moving). Uses the latest dated geometry per event; Point coords direct,
Polygon reduced to first-ring centroid. Flame-teardrop billboard (new
lib.flameGlyph, drawn in #ff7a1a with dark outline, shared canvas), aggressive
label translucency so dense California/Australia clusters stay legible, cap 500.
HUD row "Wildfires (NASA EONET)".
PITFALL handled: EONET mislabels Content-Type as application/rss+xml but the
body is JSON — we call res.json() and never gate on the header.
Verified in browser: 500 fires, all finite positions, glyphs render over
North America, zero console errors.
