- weatherSim config flag (default false): cycles through
['sunny','cloudy','stormy','night'] every weatherSimInterval ms
instead of pulling open-meteo
- Debug-panel buttons: Sunny / Cloudy / Stormy / Night for
instant manual switch; Auto-Cycle toggle, Stop, 5s/15s cycle
- Cleanup: removed duplicate unwrapped tick() in the init block
(the wrapped one already starts the rAF chain)
The sim keeps the existing 5-minute palette transition between
states, so you still see the colour shift rather than a hard cut.
Raymarches a horizontal cloud layer (28 steps, 4-octave 3D fBm).
Camera path is sinusoidal in altitude so the view dips into the
cloud deck at intervals for a 'fly through the edges' feel.
Density threshold from weather: sunny -> sparse, stormy -> overcast.
Renderer is selected via CONFIG.renderer ('clouds2d' or 'clouds3d').
The 2D WebGL renderer now creates its own <canvas> overlay inside
the target element, instead of expecting the target to already be a
canvas. This fixes 'canvas.getContext is not a function' when the
target is a <div>.
