Permanent single-file HTML site for the Brooklyn Museum exhibition Monet & Venice (Oct 11 2025 – Feb 1 2026). This version refines the experience with full mobile image protection, lightbox navigation, a redesigned wall-text toggle, exhibition context section, and a live countdown timer to 2075. The work remains immutable, self-contained, and streaming-only from Arweave. Supersedes v4.1 as the canonical edition.
