  GLOBAL STYLES
  -------------
  Shared across every page: reset, typography, layout, nav, footer,
  buttons, cards. Reads all colors from CSS variables defined in
  theme-default.css / theme-plantanapp.css (linked before this file).
  Page-specific files (home.css, services.css, ...) only add styles
  for content unique to that page.
