M0.5: detailed scenery, mountain/sea-cliff boundary, Godot 4.7
Scenery (all procedural, seeded, no imported assets): - Terrain shader: grass/dry grass/dirt/sand/rock strata/snow + detail normals - 5 tree types, faceted mossy rocks, cliff outcrops, sea stacks, bushes, logs and stumps, batched as MultiMesh per 48 m cell - Wind-animated grass and flowers streamed in tiles around the player - Lake (depth-shaded water with shore foam), ocean to the horizon, cloud sky shader, volumetric fog, glow, softer shadows - Swimming: float at the surface, swim-jump to climb out World bounds: - Steep mountain rim with an invisible wall partway up; one side opens to a sheer sea cliff with the wall 1 m inside the edge; whole chunk is an island so the mesh edge is never visible - Respawn safety net if the player leaves the walkable area or the map - Fix: the cliff edge now tracks the wall in the headlands (it used to drop away inside the wall, leaving a pit with lake water hanging over it) Tests: tests/test_boundary.gd (24-direction escape attempt) and tests/test_terrain_edges.gd (no ground below waterline near the wall). Upgrades the project to Godot 4.7 (project.godot rewritten by the 4.7 importer, .uid files added) and documents it in the setup guide.

## World controller.

## Owns spawn ordering so the player never falls through ungenerated ground:
|
||||
## waits for the terrain to finish building, then drops the player onto the
|
||||
## surface height and lets gravity settle them. Also tells the props where the
|
||||
## ground is so they sit on it instead of floating.
|
||||
## waits for the terrain, places the scenery, then drops the player onto a dry,
|
||||
## flat spot facing the lake. Also aims the sun, and respawns the player if they
|
||||
## somehow leave the map or fall below it (a safety net behind the mountain rim
|
||||
## and invisible wall in terrain.gd).
|
||||
##
|

## Dev hook: `godot --path . -- --shot=/abs/prefix` renders a few fixed views to
|

## <prefix>_<view>.png and quits. Handy for checking visual changes.
