feat(webapp): the canvas, the last item of lot D - #188

GET /api/v2/libraries carried accepts_uploads and nothing for the canvas, whose flag has been a door of its own since #158. A client could not tell a library open to loops from one closed to them, so the web client had two bad choices: offer a canvas everywhere and learn the answer only after sending the whole file, or read accepts_uploads for both and hide the canvas in exactly the library the flag was split for, one that refuses audio and takes loops. LibraryAccess now carries accepts_canvas beside accepts_uploads, read from the same row. The guide had no word on the canvas at all; it gains a section on the six routes, who may place a loop, what the server keeps, how each refusal answers, and the fact that the ticket is also how a client asks whether a track carries one. The new test reads the list with the flag on and the upload door shut, then with the flag off. Proven by inversion: mapping accepts_canvas from the accepts_uploads column fails it on its first assertion.

The last item of lot D. RFC-009's six routes have been on the server since #157, and the web client used none of them. The tag editor gains a canvas panel. An owner or a manager chooses an mp4 or webm file and it goes whole, as raw bytes, in one PUT; the panel then reads the loop back through a ticket rather than trusting the answer, previews it, and can take it away. Each refusal is said in words, because a full quota, a file over the ceiling and a file that is not a short loop call for three different things. Where the operator has not opened the library to loops the picker is withheld and removal is not: the server does not gate removal on that flag, and the screen must not strand what the server would release. The Now playing page lays the loop over the cover the way the desktop does: muted, looping, out of the tab order and the accessibility tree, with the cover underneath keeping its name. Nothing is asked of the server when the viewer prefers reduced motion, and a loop the browser cannot play leaves the cover showing instead of an empty frame. No field on a track says it carries a canvas. Minting the ticket checks the link, so the ticket is the question: canvasUrl reads a 404 as none and throws anything else, so a server that failed to answer is never taken for a track without a loop. The playing page had no end-to-end test before this one, and its lyrics were answered by the catch-all track mock, which crashed it. The mock now answers lyrics with an empty list. Proven by inversion, one at a time, each restored and checked: - the closed-library gate forced open fails the closed-library test; - removal gated on the flag fails it as well; - mayPlaceCanvas reading accepts_uploads fails the placement test; - reduced motion ignored fails the playing page test; - no fallback on a video error fails it too; - canvasUrl throwing on 404, or swallowing a 503, fails its unit test.

The last item of lot D. Tag corrections, uploads and the canvas are all in the web client now, and the note says the one thing about the canvas a reader would otherwise look for in vain: no field on a track says it carries a loop, so the client asks through the ticket.

The canvas in the web client — the third and last item of lot D in
