Original (made for this project, no third-party content): the 20 appliqué motifs, patch prints, the Bobbin spool
characters, needle, thimble, buttons, pincushion, ribbon rosette, spool clock and the "thread lettering" title glyphs
(procedural canvas drawing in public/linkup-art.js and public/linkup-render.js), and the cover / banner SVGs in
public/assets/covers/linkup*.svg (drawn from the same art code; they embed dark_wood.jpg and the Secoline font listed above).
