Clicking a gallery image now opens a dedicated viewer instead of dumping you on the raw file. - GET /b/<name>/view?f=<img> — full-viewport viewer (registered before the file catch-all so /view wins; non-image f 307-redirects to the raw file, traversal and missing f 404). - Fit (downscale-only) / 1:1 (natural pixels, scroll-to-pan) toggle that only appears when the image is larger than the viewport — when it already fits, Fit ≡ 1:1 so the toggle is hidden. Re-evaluates on resize. - Download button + ✕/Esc back to the gallery. Australis-themed, progressive JS (degrades to fit-only, no-JS still shows the image + download + back). - 5 new tests (34 total, all green); verified Fit/1:1/hidden-toggle states in a real browser.
