Release v0.5.2

Added new preset: Pitch Black with tuned low-light settings from captured profile screenshots.
Added strict host-verified ShaderPlayground sync handshake (host->client):
- explicit client state machine (Disconnected, AwaitHelloAck, AwaitSnapshot, Synced, Stale)
- v2 message flow (Hello, HelloAck, StateRequest, StateSnapshot)
- nonce, session-epoch, revision, and state-hash validation
- duplicate/stale/gap snapshot handling with automatic resync requests
Removed dependence on first-sender authority pinning for shader sync acceptance.
Added explicit host identity verification using lobby owner SteamID + player-panel sender mapping.
Added host migration/session change detection and forced re-handshake behavior.
Added built-in in-game handshake diagnostics in Tools tab:
- live sync state + reason
- expected host sender/steam IDs
- active epoch + accepted revision/hash
- rolling sync event log + clear/status actions
Added sync logging config controls:
- Debug.EnableBuiltInSyncLog
- Debug.SyncLogToBepInEx
- Debug.SyncLogIncludeKeepalive
Updated automated tests for new sync policy behavior and cadence handling.
Synced package metadata/version fields to 0.5.2.

Release v0.5.0

Major ShaderPlayground revamp focused on standalone workflow:
- retired active SessionVisualLab bridge publish/consume path
- disabled VisualLab ownership handoff behavior in runtime apply logic
Reworked F10 UI into tabbed pages:
- Core
- Effects
- World
- Quality
- Presets
- Tools
Added new effect channels:
- Noir
- Vapor
Added built-in quick presets:
- Clean
- Cinematic
- Dreamscape
- Noir
- Neon Vapor
- Stormfront
- Retro TV
Expanded synced state payload with Noir/Vapor fields for host profile sync.
Improved menu ergonomics:
- drag window from anywhere
- reset button always visible in footer
Updated package metadata and docs for the standalone model.

Changed otAPI packaging to soft dependency behavior:
- Thunderstore metadata no longer hard-requires officer_balls-otAPI-1.0.2
- otAPI controls remain available when otAPI is installed and integration is enabled.
Updated README dependency wording to match runtime behavior.
Documentation correction pass to match current runtime behavior:
- Fisheye/Breathing/Scan Lines active effect set and ranges
- save/load/reset workflow
- retired Dreamy Hypnosis runtime behavior.
Added explicit desktop pet mode suspension (OverlayManager.ResolutionMode == Desk) in scene-suspend guards.
Added compatibility hardening so visual hooks avoid non-game/aux render-texture camera targets.
Synced package and assembly version metadata for publish.

Added Dreamy Hypnosis pack (procedural/no-asset):
- DreamWarp
- Soft Chromatic Drift
- Hypno Vignette Spiral
Added Hypnosis controls and presets in F10 UI:
- Lullaby
- Float
- Deep Hypnosis
- plus per-parameter sliders for intensity/speed/warp/spiral/color blend.
Added no-flicker safety clamps for hypnosis motion speed and modulation ranges.
Added otAPI controls for full Dreamy Hypnosis section.
Extended synced profile payload with hypnosis fields:
- HypnosisEnabled
- HypnosisPreset
- HypnosisIntensity
- HypnosisSpeed
- HypnosisWarpAmount
- HypnosisSpiralAmount
- HypnosisColorBlend
Added client capability handshake bit for hypnosis support, and host-side compatibility fallback so unsupported clients are not forced hypnosis-only fields.
Updated fullscreen shader lookup order to try Hidden/ShaderPlayground/HypnosisComposite first, with existing safe fallbacks unchanged.
Version bump to 0.4.0.

Added "Pro pass" world overhaul controls:
- Enhanced sky + lighting tuning.
- Cloud layering and density control.
- Weather mood system (Auto, Clear, Golden, Overcast, Storm, Dream) with daily auto rotation.
- Realistic water override controls (clarity, wave strength, reflection boost).
Added AA and image quality presets:
- Off / FXAA / SMAA / TAA / CAS-style mode.
- CAS-style sharpening control.
Added runtime material/shader scanner:
- Scene-level shader inventory.
- Water/cloud/sky candidate discovery with quick logging.
Expanded profile sync payload and host-authoritative replication for new world + AA controls.
Added new presets:
- Realistic Water
- Storm Front
Updated otAPI controls to include sky/weather/water/AA settings.
Version bump to 0.3.0.

Added a complete runtime profile stack with four effects:
- CRT/VHS
- Dream Bloom
- Comic/Sketch
- Heatwave/Refraction
Added URP-safe fullscreen shader-pass path with pooled command buffer usage.
Added hard fail-safe behavior: shader path auto-disables on runtime exception.
Added automatic volume-only fallback mode when shader pass is unsupported.
Added host-authoritative sync protocol with:
- revisioned state
- sender identity validation
- payload size bounds checks
- authority pinning on clients
Added client opt-out toggle (AcceptHostSync) while keeping sync enabled by default.
Added SessionVisualLab bridge hook (TryPublishSessionVisualStateFromHost) and bridge-sync toggles for clients without SessionVisualLab.
Added outbound bridge publish from ShaderPlayground host state into RejoinStateRecovery / SmartCheckinPrompts / FishingTackleboxJournal bridge channels.
Added preset operations in UI:
- apply built-in preset
- save slot
- load slot
- reset defaults
Added notification throttling to prevent slider spam.
Added otAPI control registration for core toggles and effect parameters.
