SeekQuote Web v0.1.17

VIDEO EXPORT REBUILT
- Final video is no longer made from an iPhone/Chrome MediaRecorder movie.
- Each completed slide is rendered as a PNG.
- The PNG slides are uploaded to build-video.php.
- Server FFmpeg creates a fresh H.264/AAC MP4 directly from those still images.
- Default timing remains the selected seconds per slide (3 seconds in the normal workflow).
- Send to Phone also uses this new server-built MP4 before uploading to Serial Progress Seeker.
- The QR/direct-phone transfer flow is retained.
- RiK profile persistence and script history are retained.
- For reliability in this first server-stills build, video transitions are clean cuts even if Blend/Flip is selected.
