- Add runtime_config.php: credential store backed by runtime_config.json
(gitignored). Falls back to .env values so existing envs need no migration.
- Add admin_api.php: status / test_kling / update_kling endpoints gated
behind ADMIN_EMAILS allowlist. Accepts Bearer idToken when SSO enabled;
uses mock dev@localhost when SSO disabled.
- config.php: replace KLING_ACCESS_KEY/SECRET_KEY defines with ADMIN_EMAILS
- kling_api.php: read credentials via getKlingCredentials() on every request
so rotations take effect immediately without a server restart
- All .env templates: add ADMIN_EMAILS= (dev@localhost populated in .env.local)
- AdminSettings.jsx: modal with masked status, Test Connection, Save Credentials
- AppContent.jsx: admin status check on mount; Settings gear shown to admins
- Fix production URL in .env.production/.env.example (optical-prod.oliver.solutions)
- .gitignore: exclude backend/runtime_config.json

- 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.

Kling image2video endpoint expects:
image: "<base64>" (no data URI prefix)
image_tail: "<base64>" (optional, for interpolation)
Not image_url/image_tail_url with data URIs.

The Veo predictLongRunning endpoint is a predict-style API (not
generateContent) and expects image data as:
{ "bytesBase64Encoded": "...", "mimeType": "image/jpeg" }
The previous session switched it to inlineData (generateContent format),
causing the API to reject it with:
"inlineData isn't supported by this model"

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.

Old: `up -d --build` stops old container before building → if build fails, service is down
New:
1. `build --no-cache` — full rebuild, fails without touching running container
2. `up -d --force-recreate` — only runs if build succeeded
3. health check after start to catch silent failures
--no-cache ensures PHP/JS file changes are always picked up (no stale layer cache)

Kling:
- camera_control.type: use preset name directly (down_back etc.), not 'predefined'
- camera_control.config: all 6 integer fields required even for preset types
- duration: cast to integer (API rejects strings)
- I2V images: use image_url/image_tail_url with data URI prefix (not plain base64 in image/image_tail)
Veo:
- image/lastFrame: use inlineData format (Gemini API), not bytesBase64Encoded (Vertex AI)
- durationSeconds: send as string "4"/"6"/"8", not integer
Docker:
- Add uploads.ini: post_max_size=100M, upload_max_filesize=100M, memory_limit=512M
(ini_set cannot override these at runtime in php-fpm)

All backend PHP files require config.php as their first include.
It was gitignored and missing, causing PHP fatal errors that produced
empty responses — breaking JSON parsing in the frontend.
The new config.php has no hardcoded secrets; it reads all values
(GEMINI_API_KEY, KLING_ACCESS_KEY, KLING_SECRET_KEY, SSO_*) from
the .env file via env_loader.php.

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
