/* ───────────────────────────────────────────────────────────────────────────
   Padum Playground — PADUM DIVING theme.

   Tokens lifted from the production theme at
   padum-diving.com/wp-content/themes/padum/assets/css/padum.css (v1.4.0),
   by way of gradientfactor.padum-diving.com: the deep-ocean page gradient,
   white glass cards, Oswald display over IBM Plex Sans, coral actions, and
   the 6/10/16/pill radius scale.

   The live site is dark only, so this page is too. Keeping the values
   identical to the sub-apps' own theme is the point -- the hub and the tools
   it links to should not look like two different products.
