   EMENDARE v4 — "the site is a bid set that takes itself off"
   One component set, themed by tokens:
     body (default)        → Emendare parent: drafting paper / charcoal
                             ink / grease-pencil orange (drawing set)
     body.theme-luserne    → Luserne: same material world, product voice
     body.theme-testiphai  → TestiphAI: near-black / teal
   `.invert` on a section is the MATERIAL SWITCH: the night-shift sheet
   (charcoal ground, paper type). Flat fills. No gradients. Sharp corners.
