Client-side GL Transitions v1 across all three players with never-blank degradation: shader lib + generated manifest + real-WebGL CI, transition-as-widget normalization, persistent WebGL/GLES2 compositors (web/Tizen/native Android), image↔video wipes, SSRF-hardened media proxy, decode-gated image preload, dashboard picker. Fixes the playlist change-fingerprint that dropped transition edits. Alpha + on-device soak validated.
