What to do

Decisions 7 and 8 of the workshop note (land-of-lor/docs/design/2026-08-18-ground-look-and-levels-workshop.md).

ground_mesh.gd: is_peak becomes stack_level(x, y) — the Chebyshev distance to the nearest cell that is not the same hexagram (or out of bounds), capped at MAX_STACK = 2; the Volcano (Fire over Mountain) matches any Mountain flavour. mountain_instances() returns stack (0..2) and shape (cone | boulder); Earth over Mountain (kw 15) is the boulder.
area_view.gd: two MultiMeshes — cones at three heights (MOUNTAIN_HEIGHT, peak, double peak in world_units.gd), boulders a low-poly rounded square block generated in code (a superellipsoid, one function) at three sizes; the volcano cap on top of whatever height its cone reached. Both lit, both standing on the cell’s surface (002’s levels).
Content: repaint the Badlands range in game/content/areas/the-badlands.ground.json — a one-flavour cone range with the volcano at its centre, and a separate boulder field of kw 15 — with the area editor or paint-ground, then load-world on the next deploy.
Tests in test_runner.gd for stack_level (edge, ring, double ring, mixed flavours, the volcano exception, the cap).

Definition of done

Shots of the repainted Badlands range and a boulder field in docs/handoff/ground-look-and-levels/; tests green; committed and pushed.

What was done (2026-08-18, laptop workshop session)

Built and shipped the same day, folded into the levels work. Same-flavour stacking as one multi-source flood, MAX_STACK = 50 (Kris: “why the hell not”), the Volcano matching any Mountain flavour so it crowns a range; what stands on a cell is data (shape: cone / volcano / boulder — a code-built rounded block — or nothing for the five undefined flavours, still impassable); one MultiMesh per shape on the cell’s surface. The Badlands re-sculpted as a deterministic preset (Kris: “nothing there is sacred”): two stone plateaus with three ramps up, the lake as the deep level with two ramps down in notches, a 5×5 boulder square mountain, a one-flavour cone range crowned by its volcano — validated, every ramp rising, every area reachable; load-world run on the droplet.
