Permanent single-file HTML site for the Brooklyn Museum exhibition Monet & Venice (Oct 11 2025 – Feb 1 2026). Version 4.5 restores correct playback duration and instant chapter seeking, lost when arweave.net's serving layer stopped reporting content length and honoring range requests, while keeping the artifact light enough to load instantly on any connection. The player carries its own authoritative duration and never consults the browser's reading; the complete 36-minute composition is fetched into memory in the background and playback switches seamlessly to the local copy, making every seek instant and movement tracking exact in both directions. If the network falters, streaming continues unaffected. Every artwork address is unchanged from v4.3. Supersedes v4.3 as the canonical edition.
