GPU render passes for CC Particle World / Systems II, Particle Playground,
CC Ball Action, CC Pixel Polly, CC Scatterize and Curl Noise (fx_particles,
chunked multi-pass raster); Shatter wireframe views, Foam extras, Timewarp
with a Matte Layer, strong Warp Fisheye/Twist (CPU f64 inverse map) and
custom .ocio configs no longer fall back to the CPU. CPU refactors pinned by
particle_golden / timewarp_golden / sim_golden hashes.

CC Rainfall, Snowfall, Star Burst, Bubbles, Drizzle, Hair, Mr. Mercury,
Caustics, Wave World, Foam, Shatter, Card Dance and Card Wipe render on the GPU
(fx_sim.rs / fx_sim.wgsl). The per-frame simulation / layout stays on the CPU
and is shared with the CPU effect through plans (effects::sprite_plan,
piece_plan, bubble_list, mercury_blobs, drizzle_drops, wave_world_plan,
caustics_setup); a tiled item rasteriser composites sprites, bubbles, blob
fields and textured pieces in the CPU's order and shading. Layer-dependent
sprite colours (refracting rain, star-burst and hair roots) are sampled per
pixel; piece plans read the frame back once.

- Particle Exploder, Ephemeral Property Mapper (operators), Affects groups on every
producer / force / mapper (source, selection map, characters, age + feather).
- Full mapper target list (angle, torque, scale, gradient velocity/force, lifespan,
character, font size, time offset, scale speed...); old saves remap by label.
- Cannon / Grid text particles (stroke font), Auto-Orient Rotation, Layer Map draws the
map layer per particle with Time Offset Type / Time Offset.

Particle Playground: cannon, grid, layer exploder, layer map, gravity,
repel, wall and persistent property mapper; deterministic, stepped from
t=0 through the checkpointed SimCache.
