A Bambu Studio or OrcaSlicer 3MF names the filaments its plates use, but reading that means shelling out to Python, so it can't be done per page load. A background pass — in the same loop as thumbnails and fingerprints — reads it once per model into models.filaments, which turns "what can I print now" into a comparison of two lists. Adds a Filament page for the spools on hand: material, colour, brand and grams left, edited in place. Matching is on material only; a project's exact colours would make almost nothing printable, and a different colour still prints. Measured on the dev library: 10 models read with no errors, the two Bambu projects resolving to four PLA colours each, and no plate images written because the reader skips --images and queues behind anything interactive. Not done yet: nothing in the library view uses this — no "printable now" badge or filter — and the Filament page itself has not been seen rendered, because the local preview browser has no session.
