* 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
