/* card_backb.css: ArtCards(TM) back, Variant B. 2026-10-17, behind build flag ARTINTEL_QR (scripts/artintel/card_qr.py).
   ONE fixed layout at the card's 5:7 (63.5:88.9) ratio. Everything is visible with no scroll, and type scales with the card width
   (container query units on the back face), with a 10px floor. Card-internal, fixed colours: identical in site light and dark mode.
   Order: identity -> bio (6-line budget) -> up to 3 key facts -> [Links . N] [Claim] -> image credit -> foot (badge + legal | QR). */
