6. `client/webapp/js/engine/world_renderer.js`

## Exploration Scope & Instructions
Investigate the world canvas visual fog overlay and entity suppression:
1. Examine `client/webapp/js/ui/war_fog_renderer.js` and `world_renderer.js`:
   - Visual Shroud Rendering:
     - `UNEXPLORED` (0): pitch black overlay (`rgba(0, 0, 0, 1.0)`) or textured dark shroud.
     - `EXPLORED_FOGGED` (1): semi-transparent shadow (`rgba(0, 0, 0, 0.55)` or desaturated veil).
     - `VISIBLE` (2): fully illuminated (`rgba(0, 0, 0, 0.0)`).
     - Viewport culling for fog tiles: render only tiles intersecting current viewport.
     - Smooth radial gradient falloff or smooth tile alpha transitions.
   - Entity Suppression:
     - Monsters, NPCs, and dynamic loot items residing on tiles where `WarFog.getFogState(tx, ty) !== 2` (`VISIBLE`) MUST be suppressed from rendering in `world_renderer.js` / `monster_system.js`.
     - Static terrain and persistent props in `EXPLORED_FOGGED` (1) remain rendered under the dark veil.
     - Waypoint icon and unlocked Boss Gate visibility rules.
2. Code constraints:
   - `client/webapp/js/ui/war_fog_renderer.js` must remain $\le 250$ lines (Soft cap 350, Hard cap 500 lines).
   - Zero heap allocation per render frame.
3. Deliver a detailed technical report in `report.md` and self-contained `handoff.md`.
Notify parent when complete.

MANDATORY: Read the authoritative user request at:
c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md (specifically section ## 2026-10-01T19:19:13Z - R4).
Also consult c:\Projects\FreeExile\GEMINI.md, c:\Projects\FreeExile\AGENTS.md, and c:\Projects\FreeExile\.agents\teamwork\orchestrator_11\PROJECT.md.

Investigate world canvas visual fog overlay and entity suppression:
1. Examine client/webapp/js/ui/war_fog_renderer.js and world_renderer.js:
   - Dark shroud rendering: 0=UNEXPLORED (pitch black), 1=EXPLORED_FOGGED (semi-transparent shadow), 2=VISIBLE (clear).
   - Entity suppression: monsters, NPCs, and dynamic loot items outside VISIBLE tiles MUST be hidden.
   - Viewport culling for fog tiles with smooth transitions.
2. Ensure war_fog_renderer.js stays <= 250 lines (Soft cap 350, Hard cap 500 lines).

Write report.md and handoff.md in your working directory and notify parent when complete.
