Spread spectrum v2: independent per-channel embedding with round-robin bit distribution, preserving spatial stereo/surround mix. Adaptive chip tiers (256/512/1024) trade capacity for lossy codec robustness. LFE channel skipped for 5.1+ layouts. v2 header (20B) with backward- compatible v0 decode fallback. Environment toggles (STEGASOO_AUDIO, STEGASOO_VIDEO) gate audio/video features for minimal builds (e.g. Raspberry Pi image-only). Values: auto (default, detect deps), 1/true (force on), 0/false (force off). Web UI fixes: accordion defaults to step 1 on load, chevron arrow styling, required attribute toggling for audio carrier type switch, "Images & Mode" renamed to "Reference, Carrier, Mode".
