The image never built: CASPAR_URL pointed at a v2.3.3-stable Linux tarball that CasparCG never published (2.3.x is Windows-only; Linux builds start at 2.4.0, and 2.4.1+ ship only as .deb). Rewrite to install the 2.5.0 noble server + CEF debs on an ubuntu:24.04 base (Node 20 via nodesource), letting apt resolve the GL/ffmpeg/openal runtime deps. Binary install dir is discovered from the deb file list and symlinked to /opt/casparcg so the entrypoint + config still run from there. Move CasparCG log/data dirs to /media (writable mount) since the install dir may be read-only. NOT runtime-validated: the 2.5 casparcg.config schema and the AMCP consumer syntax (ADD <ch> STREAM/FILE) were authored against 2.3 and must be smoke- tested against 2.5 before a channel start can be trusted.
