Reported from the library: a four-colour AMS bookmark showed as "printable now"
against a single spool of Jade White. The matching collapsed the project's four
slots into the set of materials it used — {PLA} — and then asked only whether a
PLA spool existed. A sixteen-colour model would have passed the same way.
Ignoring colour is right: printing a bookmark in red instead of white still
prints. Ignoring slot count is not: four slots need four spools loaded. Matching
now counts slots per material and reports the shortfall — "needs 3 more PLA",
and on the model page "Needs 4 × PLA. You have 1 of 4 PLA."
The tests carried the same mistake, asserting that one spool satisfied a
multi-slot project, so they are rewritten around the reported case.
Also documents the feature in the README, which had no entry for it at all.

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.
