- Preload stance icons at _ready() into cache Dictionary
- Null-guard shader + theme loads with push_error() + early return
- Guard _icon_mat.set_shader_parameter inside if _icon_mat:
- Icon size 18→20px per D-086, container height 44→46px to fit
- Add _apply_stance test coverage (known + unknown stance)

Replace text-only stance labels with SVG icons + tint shader per D-086.
Alpha-mask shader swaps color at runtime via ShaderMaterial parameter.
Icons: walk, crouch, careful, sprint at 18px inside ImplantPanel row.
Also fix stale UILayer/HUD test path in test_ui_framework_sprint15.

Circular 160px diegetic insert overlay on CanvasLayer 10. Nearby
POIs as colored dots (diamond=danger, square=evidence, circle=default),
distant POIs as directional border arrows. Player centered, fixed-north.
Moved from UILayer to InsertOverlay per D-013/D-049.

The 1200px value was a deliberate readability decision, not a spec
violation. Reverts the incorrect 640px change from round 1. Updates
comment and regression test to match.

Remove stale smoothing re-enable comments from main.gd (Hoshe #1).
Add DIALOGUE_MAX_WIDTH=640 regression test (Hoshe #2).
Extract GROUND_FLOOR const in tile_renderer (Tyre #3).
Clean up entity_renderer migration comment (Hoshe #3).

Critical: DIALOGUE_MAX_WIDTH 1200 → 640 to match D-076 spec.
tile_renderer: clarify z = server floor level, not scene z_index.
Add z-filter unit test (tiles at z!=0 must be skipped).
Camera test: is_equal → distance check for float safety, convergence
test frames 40 → 120 for robustness at lower smoothing speeds.
Teleport: remove redundant first snap in _teleport_transition (the
camera block in _process handles it via _teleport_in_progress flag).
entity_renderer: document y-sort bottom-anchor migration path.
