-- Saved as `[worldtint] active/bind/world/sky/wr..wb/sr..sb`.
+- Saved as `[worldtint] active/bind/world/sky/prop/wr..pb`.
+- Particle tint is deliberately not implemented: HL2's old particle manager
+  draws per-vertex coloured IMesh quads, and SpriteCard/TF2-style particles
+  take colour from per-particle vertex data, so `IMaterial::ColorModulate`
+  does nothing for them. It needs a hook in the client particle render path.
+
+### Fog
+
+- `src/world.cpp` `fog_update()`, driven by the `fog_override` engine command
+  family through `IVEngineClient::ClientCmd` (same safe path as fullbright).
+  No render hooks.
+- Enabled: `fog_override 1`, `fog_enable 1`, `fog_color`, `fog_start`,
+  `fog_end`, plus `fog_enableskybox` / `fog_colorskybox` /
+  `fog_startskybox` / `fog_endskybox` when skybox fog is on.
+  "Remove fog" issues `fog_enable 0` instead.
+- Disabled: `fog_override 0` restores the map's own fog controller.
+- End is clamped above Start. Re-applied on level change via
+  `fog_invalidate()`. Saved as `[fog] active/bind/r/g/b/start/end/skybox/disable`.
