   AquaMagis captive portal

   Everything brand-related lives in the :root block below — changing those
   values rebrands the portal without touching anything else.

   No web fonts, no CDN, no external anything: the Apple/Android captive
   mini-browser can only reach hosts in the UniFi walled garden, so an external
   asset would leave the page half-rendered on exactly the devices that matter.
