- camera_control: only kling-v1 and kling-v1-5 support it (not v3)
- For preset types (down_back etc.), config must be absent — only
'simple' type uses config fields
- camera_control and image_tail are mutually exclusive in I2V
- cfg_scale not supported by kling-v2.x models — now skipped
- duration sent as string to match API examples
- v3/v3-omni removed from camera control UI list

Camera/motion control is only supported by kling-v1, kling-v1-5,
kling-v3, kling-v3-omni. Backend silently drops the camera_control
field for all other models. Frontend hides the camera control UI
and auto-clears the selection when switching to an unsupported model.
New models added: kling-v3-omni, kling-video-o1, kling-v1 (cam ctrl),
kling-v2-master. Duration validation loosened for v3/v3-omni (3-15s).

Client-side Gemini calls were hitting the frontend API key's rate limits
and exposing the key in the browser. The optimizer now POSTs to
video_api.php (action=optimize_prompt) which calls Gemini server-side
using the backend key.
Rate-limited responses (429) silently fall back to the simple prompt
generator without showing an error.
Removes the @google/generative-ai import from VideoGenTab.

nginx inside the Docker container defaults to 1MB body limit —
base64 image payloads exceed this and return a 413 HTML page,
causing the "Unexpected token '<'" JSON parse error on video_api.php.
Gemini 429 rate limit errors on prompt optimization now fall back
silently instead of surfacing an error to the user.

After changing the video URL prefix to /lux-studio/api/generated_videos/,
the old /generated_videos/ check caused a false-positive validation error.

Kling video generation:
- Full T2V, I2V, extend, and lip sync workflows via Kling API
- V3, V2.6, V2.5 Turbo, V2.1 Master, V1.6 model support
- Resolution selector (720p std / 1080p pro) with model constraints
- Native audio toggle with dialogue input for Kling
- Video ID tracking for extend and lip sync chains
- Camera control presets (pan, tilt, arc)
Prompt optimizer rework:
- Intent-preserving refinement (camera, action, mood are sacred)
- Mode-aware: T2V adds subject/environment detail, I2V describes only motion
- Reference images analyzed for content, not re-described
- Platform-specific quality anchors woven into positive prompt
- Negative prompts removed from optimizer (positive-only approach)
- 15-60 word target for concise, effective prompts
Backend fixes:
- Gemini responseModalities: ['TEXT', 'IMAGE'] for Flash model compatibility
- Veo first-frame resize to exact target dimensions (prevents letterboxing)
- Session directory re-creation in saveImage (auto-cleanup race condition)
- Kling API error logging with HTTP codes and payload details
- Lip sync endpoint updated to /v1/videos/lip-sync with video_id
Frontend stability:
- Tab persistence via CSS hidden (generation survives tab switches)
- Project switch protection (confirm dialog when generation in progress)
- Retina thumbnails (480px/q0.8) for library grid — prevents OOM crashes
- Thumbnail backfill migration for existing project items
- Project items refresh on tab visibility and after save
- 1:1 aspect ratio container for Kling videos
- Expanded video view matches library modal behavior

PNG: Remove card backgrounds, borders, header bars, and empty
annotation text. Just images in a grid with a small frame number.
PDF: Reduce margins and label reservation to maximize image size.
Frame number and annotation condensed to one small line below.

Tabs now float between logo and user info via justify-between,

Slate-925 panels are nearly invisible against black/60 overlays.
Modals need to be clearly visible, so they use slate-800.

Custom slate-925 (#080d1b) sits just one shade above the 950 ground,
making panels barely visible. The content is the interface, not the
chrome. Reverts the inverted-depth experiment.

Page ground from bg-slate-950 to bg-slate-800. Content panels stay
bg-slate-900, creating inset wells rather than floating cards.
Like a Braun control panel with recessed dark areas.

Zone markers (Preset, Camera Body, Lens Kit, Duration, etc.) get
uppercase + wide tracking like Braun hi-fi category labels. Modal
form labels and interactive toggles stay sentence case.

Second typographic voice for timestamps, dimensions, file sizes,
session IDs, costs, word counts, resolution specs, and version number.

Remove all opacity variants (bg-slate-900/50, bg-slate-800/50, etc.) in
favor of opaque tones. Inputs standardized to bg-slate-800 (Elevated).
hover:bg-slate-800 promoted to hover:bg-slate-700 (Interactive tier).

Off-white toggles did not improve things -- gold selected state

Replace bg-cinema-gold with bg-slate-200 on all 21 toggle/selector
buttons. Gold now reserved exclusively for primary CTA buttons
(Generate Image, Generate Video). Creates quieter UI that lets
generated images and video stand out.

Strip panel/card wrapper borders, section separator borders, tooltip
borders, and modal borders. Remaining borders are all functional:
input fields, focus states, status indicators (green/red/amber),
dashed upload zones, active selection states, and type badges.

DM Sans at weight 400 is clean and readable — hierarchy now comes

- Add kling-v3 and kling-v3-omni to model selector and backend validation
- Set V3 as the new default model (was V2.6)
- V3 Omni includes built-in audio generation

Integrates Kling AI as a second video engine in the Video Gen tab with
three cinema-relevant workflows: Generate (T2V/I2V with camera control),
Extend (video extension up to 3 min), and Lip Sync (image + audio).
Backend: New kling_api.php with pure PHP JWT auth, all workflows, async
status polling, and CDN video download. Env files updated with Kling
credential placeholders.
Frontend: Engine selector toggle, workflow-specific settings panels,
Kling polling, engine badges in ProjectsTab, rerun support.
Also includes image model toggle changes (Gemini Pro/Flash).

Features:
- Custom user presets: Create, edit, delete, export/import lighting presets
stored in IndexedDB (useCustomPresets.js hook, DB schema v3→v4)
- Identity protection: LLM-mediated name-to-style translation prevents
generating recognizable real people while preserving style references.
Active divergence breaks likeness convergence. Defense-in-depth across
both prompt paths + generateImage() fallback
- Video negative prompts: AI auto-generates suggested negative prompts
during Veo 3.1 prompt optimization. Collapsible editable textarea
teaches creatives what to exclude. Sent as negativePrompt parameter
- Generate Video from Library: Image preview modal now has a gold
"Generate Video" button that loads the image as a first frame reference
- Expanded preview overlays: Maximize button on generated images and
videos opens a large centered overlay (90vw, not fullscreen)
- Move items between projects: ArrowRightLeft button in Library list
and preview modal
- Preset display in Library: Shows which preset was used per generation
Backend improvements:
- video_api.php: negativePrompt passthrough to Veo 3.1 parameters,
lastFrame interpolation works with fast model (8s required)
- api.php: Exponential backoff retry (3 attempts), increased memory/
POST limits for 4K images, user-friendly 500 error messages
- enhance_prompt.php: User lighting intent now respected over preset
defaults (critical fix for night/sunset scene descriptions)
- session_manager.php: Fix images subdirectory creation race condition
Infrastructure:
- SSO made conditional via VITE_SSO_ENABLED env variable — hooks only
called when SSO is active, local dev bypasses auth cleanly
- .gitignore updated for root-level generated_videos/, uploads/,
config.php, backend/php.ini, Prompt_Studio/
- Wire up dead getNegativeConstraints() code in both prompt paths
No env files or secrets included. Production deploys via deploy.sh
using .env.production templates (SSO_ENABLED configurable per env).
