Encode/Decode UI:
- New accordion layout with 3 steps (encode) / 2 steps (decode)
- Gold step numbers with checkmarks on completion
- Dynamic right-aligned summaries as fields are filled
- Subtle gradient highlight on active accordion step
Webcam QR Scanning:
- Camera button for RSA key QR codes on encode/decode pages
- Camera button for channel key scanning
- 3-2-1 countdown capture for dense QR codes
- Proper scanner stop/restart on retry
- Backend decompression for STEGASOO-Z: compressed keys
RSA Key Print:
- Removed identifying text from QR print output
- Now prints plain QR code for discretion
Pi Image Script:
- Fixed 16GB resize to detect expand vs shrink
- Fresh images now properly EXPAND to 16GB
- Already-expanded images properly SHRINK to 16GB
UI Polish:
- Removed PIN helper text for compactness
- Fixed QR drop zone centering
- Fixed decode page element IDs for JS

Progress bar support (v4.1.2):
- Web frontend: Real-time progress during encode with phase display
- CLI: --progress flag with rich library for encode command
- Backend: progress_file parameter for async progress reporting
DCT decode bug fix:
- Fixed InvalidMagicBytesError not being caught in early-exit check
- RS-protected format (v4.1.0+) has length prefix first, not magic bytes
- Exception handler now catches both ValueError and InvalidMagicBytesError
MOTD update:
- Added sparkly header to setup.sh MOTD (matches other rpi scripts)

- Fix block calculation mismatch in DCT extract (use original dimensions)
- Change default dct_color_mode from "grayscale" to "color"
- Update DCT test to use noise image instead of solid color
- Remove debug logging from encode/decode paths
The block calculation fix ensures extract uses the same block positions
as embed for images whose dimensions aren't divisible by 8. This was
causing decode failures on the Pi web UI with 1195x671 images.
Color mode is now the default since it preserves the original image
colors. The test fixture now uses a random noise image because solid
color images cause coefficient drift during YCbCr/RGB conversion that
can corrupt embedded data.
