/* Pandora's Gate — pandorasgate.app
   Hand-written, no build step, no external requests. Surfaces are the app's own
   zinc theme tokens; the accent is sampled from the gold linework in the app
   icon (#d0b060) rather than the app's indigo UI accent, so the page reads as
   one piece with the mark at the top of it. Dark is the default, as in the app. */
