/* ==========================================================================
   Shivalik Hospital: what every page shares (tokens, base, shared pieces,
   header, footer, WhatsApp button). Each page keeps its own screens inline.
   Doctors sample site 3 (a made-up 30-bed general hospital), four pages.
   Colours and fonts: brand.json. Look D, Linen and forest, chosen by Raman.
   Corners: buttons 12 (small 10), cards 16, photos 20, icon discs round.
   One screen each: from 1024px up every length is in rem and the root size
   follows the window (16px at 1440x780), so a section that fits one laptop
   screen fits every laptop screen. Below 1024px the page simply flows.
   His standing rules (docs/preflight.md): headings one centred line just under
   the header; blocks side by side start and end level; sibling cards match;
   several calm colours; icons draw themselves; clickable cards lift.
