# Client — rendering and presentation

**Holds:** rendering, meshing, UI, input, everything the player sees.

**Boundary:** may use `Core/`. Must not depend on `Server/` internals.

## Empty this phase — deliberately

Phase 0 has no renderer. The mesher (SN/DC smooth terrain + greedy-cube builds with seam-blend,
→ D-052, `Design - Rendering - Mesher.md`) is a much later phase, and building it before the data is
right is explicitly the trap the rewrite exists to undo (D-056: *"the data is perfected before the
mesher"*).

## One thing already decided, so it is not re-litigated later

**Mesh style is per-ORIGIN, not per-material.** Natural runs mesh smooth, player-placed runs mesh as
cubes, and the same material can be both. The flag the mesher reads is `RunOrigin` on the run — there
is no mesh-style field on any material row, and adding one would be a design regression.
