* feat(core): tell which video files deserve a lighter preview copy, and at which size
* feat(studio-server): serve lighter copies of heavy playable files, a keyframe every second
* feat(core): the preview plays lighter copies of heavy videos below full quality
* style: shorten two comments
* style: shorten a comment
* style: shorten a comment
* fix(core): format the preview quality files and split the copy sizing for the complexity gate
* style: format the studio-server preview files
* fix(core): type the copy job's level as a preview quality
* chore(producer): raise the package size budget for the preview runtime growth
* fix(cli): a long video copy reports progress, resumes in 15 s pieces and stops only when stalled
* perf(core): a video copy's size box follows the stage within a fifth, not a half
* docs(cli): shorten two comments to the line limit
* fix(cli): the copy heartbeat drops a finished copy; size budgets follow the stall and progress code
* chore: size budgets rise by this change's measured bytes
* perf(studio): preview decodes hard-to-play videos at the size they are shown
Studio's copy of an HEVC or ProRes clip was made at the source's full size, so a 4K clip was decoded at 4K inside a preview a few hundred pixels wide, and back-to-back 4K clips flashed the background at their cuts. The player now reports how large it shows the composition, the runtime asks for a copy sized to the shown video (on a ladder of sizes, never above the source), and Studio stops pre-warming source-size copies. CLI play, static serving, publish and renders keep the source-size copy.
* fix(studio): sized preview copies follow zoom, hover previews and the newest size
Studio reports the preview's on-screen scale when a zoom settles and for composition hover previews, which no player measures. The runtime loads only the newest size asked for, regrows a first copy made while the frame grew, and never replaces a copy with one smaller on either side. The player's scale is measured against the frame's own layout width.
* fix(studio): keep comment shares and file sizes within the repo ratchets
* test(studio-server): end the sizing test's ffprobe options before its input
* fix(studio): hover previews report their size once their runtime is ready
