   DEYOHEALTH — site.css · WHO-style edition (v12)

   Design grammar taken from the WHO public site (who.int, fetched 2026-10):
   · typeface Noto Sans 400/500/700, headings bold, letter-spacing normal
   · palette  navy #00205c · brand blue #009ade · action blue #006cbe
              ink #20313b · muted ~#6a6a6a · surfaces #fff / #f6f7f9 / #e1e4ec
              borders #e0e0e0 / #b2b2b2
   · cards    white, 4px radius, hairline border, image with a 3px navy rule
              under it, 24px content padding
   · section headings: bold, full-width hairline rule underneath
   · buttons  rectangular, 4px radius, 2px border, bold label
   · links    action blue, underline appears on hover
   Component class names are unchanged from v11, so the 18 pages keep working.
