- Greedy meshing now bakes per-vertex AO with 4-corner sampling and an
anisotropic-diagonal split when corner AO disagrees.
- WGSL: extracted sky_dome() for hemisphere ambient sampling so vertical
faces match the sun-side sky tint at day; ambient_strength mixed by
day strength instead of a flat constant.
- Step-1 post pipeline: render scene into an offscreen color texture,
pass-through to the surface. Foundation for FXAA/shafts that will
follow.
- Input bug: merge_held() now recomputes per tick from sticky keyboard +
live touch bridge, so releasing the joystick actually stops the
player (previous OR-into-self bug ate playtests).
- Touch UI hit-zones reordered (menu/hotbar above the joystick z-index);
hotbar widened to 10 slots with tap-to-select on mobile.
- find_safe_spawn anchors on natural_surface_y so spawn is deterministic
from noise — towers built at spawn no longer climb the spawn point.
- move_axis is sub-stepped (0.45-block max) so high-velocity falls can't
teleport the player inside terrain.
