Fly mostly above the clouds with brief dips
...
Camera altitude is now driven by pow(sin,5) so the view stays at
y=2.6 most of the time and only briefly dips to y=0.9 to skim the
top of the cloud deck. Marching also skips the empty gap between
camera and cloud ceiling when looking down from above.

Tune clouds3d for low-end GPUs: 18 steps, 3 octaves
...
Reduce raymarch iterations from 28 to 18 and fBm octaves from
4 to 3 (with step size 0.55->0.85 to preserve cloud coverage).
Per-pixel cost drops by ~55% while visual density stays similar.

Add volumetric clouds3d renderer
...
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').

Make clouds2d.js theme-agnostic
...
- Remove all hardcoded fallback hex/rgb values
- Skip draw until __currentPalette is published by parent
- applyWeatherTheme now also mixes cloudShadow (was dropped)

Fix clouds2d: create own canvas element
...
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>.
