Three viewer features over the Live World sim:
* Storm follow-cam (Y): the 3D camera locks onto a weather system and keeps it centred as it
moves, by pointing along rotateZ(storm.pos,+axialTilt) (model->world) via camYaw/camPitch.
Tracked by a new stable WeatherSystem.id (assigned at spawn from sStormNextId; transient, no
RNG/determinism impact). Cycles by descending strength, off after the last; orbit-drag disabled
while following; auto-releases if the storm dissipates; wheel still zooms.
* 2D map zoom/pan: a virtual projection rect (mapViewRect = mapRect scaled about its centre +
mapPanX/Y) routes every map projection call while the scissor/frame stay mapRect (drawMapTris
now derives y from the rect, not the fixed m.pos, so both axes zoom). Wheel over the map zooms
toward the cursor (1-8x); drag pans when zoomed, else rotates mapLon; 2D picking inverts the
same rect.
* Live-clock stepper: the stepSim live body is factored into liveAdvance(dtClock,dtWeather).
'.' steps forward and ',' back by liveRate hours; backward rewinds the deterministic sky
(day/night, tides, seasons, moon phases) but holds weather (not reversible). S in Live World
aliases the forward step (no longer runs a stray tectonic tick).
All five headless suites pass; GUI build clean. Docs updated.
