/* Captive portal styling.
   Constraints that shaped this: it renders inside the OS's captive-portal
   mini-browser (no tabs, no zoom controls, sometimes an old WebView), on a phone,
   often outdoors in sunlight, held by someone waiting for their car. So: high
   contrast, large touch targets, no web fonts, no framework. */
