Add Ledger and Band template families with decor primitives

Crimson Grid, Tangerine Ledger, Slate Band and Teal Swoosh are rebuilt from
the Canva PDFs with grid and band tables that survive page breaks,
full-bleed fixed bands, pennant tabs, gradient corner swooshes with
keep-outs, Carbon icon circles, and the user's logo in the measured slot
(knockout or white chip on the dark Slate band). Adds static Poppins
500-700 and Inter fonts. Thumbnails regenerated for all eight templates;
the item-count sweeps run in their own test file.
