/* Central Valley Water Map landing page (from the design pass in design/landing_v2, 2026-10-30).
   Tokens: the neutrals and link colour are the first landing page's; the two map accents are each app's own --accent
   (groundwater app/static/style.css #2a6f4f; surfacewater app/static/style.css #236bc4, both checked >= 4.5:1 under
   white text in their accessibility passes). The header strip reuses the switcher's classes (snippet/cvwa-switcher.css)
   so the family mark looks the same here and inside both maps. No external fonts or scripts. */
