/* buycatnip.com v3 (2026-10-20, Patrick cards "retravailler le site ... il faut que ca soit beau" and "inspires-toi de
   Gifrafe ... un chat ... ni en vert, ni en blanc"). Apricot paper, night plum, ginger-cat tangerine and the violet of
   the catnip flower. Nip the cat is built from rounded blocks; its tail blocks sway one after the other.
   The memorable thing: every tool is framed like a herbarium specimen label (double rule, pressed-leaf mark).
   Own fonts (Bricolage Grotesque for titles, Public Sans for text), no external call. ASCII only. */
