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.

Godot 4.6 OpenGL3 compatibility mode does not support 'return' in
fragment(). The early returns on lines 68 and 82 caused silent shader
compilation failure, making the fog overlay render as a no-op — the
root cause of the Sprint 22 fog regression.
Restructured to if/else-if/else chain preserving identical logic.

The 5-layer fog model's deep fog sub-zone (alpha 0.55-0.70) was designed
for the old peripheral sector. After #569 removed peripheral, tiles behind
the player dropped straight to deep fog — indistinguishable from unexplored
black over dark scene tiles.
D-015 is explicit: behind = light fog overlay, art preserved, just "not
fresh." There is no deep fog sub-zone.
Changes:
- Remove dual light/deep fog alpha — all explored tiles use alpha 0.25-0.35
- Add 5x5 Gaussian blur on exploration texture to soften staircase boundary
- Use blurred exploration value for the visual transition (raw for anti-bleed)
- Remove DARK_OVERLAY constant (zone_tint handles all explored color)

Round 3 review fixes — thorough spec cleanup:
- Remove visibility_sectors from data flow (peripheral removed in #569)
- Remove player_pos uniform (cone center implicit in visibility_tex)
- Update FogState pseudocode: remove sector step, add zone tint step
- Update lifecycle diagram to match single update_from_state() call
- Fix "5-layer fog" → "3-state fog" in Files to Create and impl notes
- Mark zone tint open question as resolved (Sprint 22, D-077)
- Document filter_nearest rationale on zone_tint_tex (D-073 hard zones)
- Note low-saturation tint is intentional per D-046 Hopper test

The 7x7 Gaussian kernel (sigma 2.0) produces a 3-4 tile radius
gradient, not 6-8 tiles. Header comment now matches the function
comment and actual math.

- Widen world_seed entropy from u32 to full u64 by combining two randi()
calls (Hoshe warning #1)
- Persist world_seed to save directory and restore on resume_game() so
loaded sessions maintain D-010 deterministic replay (Tyre warning #2)
- Constrain EntanglementConfig intrigue range based on flat value so
mundane_ratio stays within D-029 spec [45,55]% (both reviewers)
- Remove dead VIS_PERIPHERAL constant and _grow_bounds() method
- Update test_client_p1 peripheral test for forward-only simplification
- Fix misleading exp_fade shader comment (filter_nearest = hard step)

Root cause: update_from_state() used visible_tiles (always empty in live
server mode) instead of visible_positions for bounds calculation. Bounds
never grew beyond 64x64, so tiles outside that area rendered as solid
unexplored black.
Fix: new _grow_bounds_from_positions() method reads visible_positions
(always populated from server snapshots). Shader fix: removed the
(explored < 0.01 && vis_raw < 0.01) guard that cut off the Gaussian
gradient at unexplored tile boundaries. Doubled blur step size for
D-066 compliant 6-8 tile soft gradient. Added debug_exploration mode
for diagnostic rendering of the exploration texture.
19 acceptance tests covering exploration persistence, bounds grow-only
invariant, gradient margin, Forward-only visibility writes, and
exploration data surviving texture resize.

Ticket #563. Light fog alpha tuned to 0.25-0.35 range (was 0.25-0.55),
deep fog alpha set to 0.55-0.70 with zone temperature tint from
zone_tint_tex (bar=warm #2a1f15, hub=cool #1a1f2e, corridor=neutral
#1a1a1a). Two Perlin noise cycles: 8-10s light, 15-20s deep.
Zone tint texture now populated per-tile from server zone_id in
fog_state.gd with preservation across texture resizes.

Reduce from 5-layer to 3-layer fog: clear (forward cone), explored
(light overlay preserving art), and unexplored (solid near-black).
Remove peripheral sector handling from fog_state.gd.
Also preserve exploration data across texture resizes — previously,
resizing the fog texture lost all explored-tile state, causing tiles
behind the player to render as unexplored black instead of light fog.

- Visible half-angle 150° → 100° (200° arc), matching average human
binocular field. Blind spot widens from 60° to 160° — genuine
vulnerability behind the character.
- Forward half-angle stays at 60° (120° arc) — binocular overlap zone.
- Peripheral zone represents combined sensory awareness: visual
periphery + subconscious sound/motion tracking, not just eyes.
- Per-character VisionConeConfig allows implants and perception modes
(D-017) to widen beyond the unaugmented baseline.
- Fog shader: smooth back-edge gradient via smoothstep blend between
Layer 2 (peripheral) and Layer 3 (deep fog), eliminating blocky
stair-stepped tiles at the rear of the vision cone.
- D-015 updated with physiological basis and per-character config.
- D-017 updated with vision cone modification by perception modes.
- D-020 updated with protocol versioning policy: PROTOCOL_VERSION
gates wire format, not gameplay parameters.
- DB backup after sprint 21 close.

Deep fog noise scroll speed 0.045/0.03 → 0.06/0.045 to match D-059
15-20s breathing cycle spec. Clamp sample_visibility() UV coordinates
to [0,1] to prevent sticky gradient at map edges.

The visibility texture has binary per-tile values (0/180/255) — bilinear
filtering alone only smooths ~1 tile, producing hard stair-stepped edges
at the LOS boundary instead of the 6-8 sim tile gradient D-059 specifies.
Add sample_visibility() with 7x7 Gaussian kernel (sigma 2.0) that
spreads the LOS boundary into a 3-4 tile radius gradient. Lower
PERIPHERAL_LOW from 0.55 to 0.08 so gradient tiles enter the peripheral
fog branch. Fix Layer 1/2 alpha discontinuity at CLEAR_THRESHOLD.
Guard against gradient bleed into unexplored tiles.

Layer 2 (peripheral): reduce peak alpha 0.55→0.38, noise 0.1→0.05,
taper noise to zero near clear boundary for a clean gradient edge.
Layer 3 (deep fog): reduce alpha range 0.78-0.90→0.62-0.76 so zone
temperature tint breathes through. Layer 5 unchanged (alpha 1.0).
Ticket: #564

Entity renderer: add framerate-independent position lerping so entities
slide between tiles instead of snapping. Tuned for Sprint snappiness
and Walk/Careful fluidity.
Fog shader: set ColorRect to transparent fallback so a shader load
failure doesn't paint solid white over the world. Track camera position
(not player position) so fog stays synced during smooth camera pan.
Restructure GLSL to avoid early return (some GPU drivers miscompile it).
Minor type fixes: typed Array[Vector2] in cursor_renderer tick drawing,
untyped Array in inventory_grid to avoid Godot typed-array cast issues.
