/* ==========================================================================
   Medical Mission of Hope to Zambia — shared site styles
   Design direction: "Borehole"

   The system is drawn from what MMHZ delivers: groundwater. Deep water
   indigo and borehole teal carry the page; copper — the material Zambia
   is built on — is reserved for actions, and appears nowhere else.

   This file is the single source of truth for the chrome every page
   shares: tokens, type, header, navigation, buttons, and footer.
   Page-specific styles stay in each page's own <style> block and should
   be written against the tokens below, never against raw hex values.
