The preview asked `derived/` for a 640-wide rung and drew it about 1900 pixels wide — stretched three times over, which reads as a poor photograph rather than as the wrong file. Raising the rung only moves the problem: the box is most of a panel wide and can be zoomed on top of that, so any rung chosen in advance is chosen wrong, and the widest one available is whatever the ladder happens to hold. The original has every pixel there is. It is also, often, a HEIC that no browser can decode — which is what av-club is for, and the platform already renders those for its own file browser through exactly this path. So there is a `/original/*` route: it resolves a path inside `originals/`, forwards to av-club's `/v1/render` with a width, and streams back something a browser can draw. It decodes nothing itself. That is the standing rule and the reason there is no image library in this plugin. Not cached on disk, like the platform's own /render and for the same reason: a full-size render is large, looked at once, and keyed on a width the panel chose. Caching it would fill a disk to make the second look at one photograph faster. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
