/* Aarti, Marigold.

   Light mode carries the festival: warm white, solid marigold blocks, and
   sindoor for the one button that moves you on. Dark mode is for the evening
   aarti beside the lamp: plum night, with marigold only on the line being
   sung. One typeface, Baloo 2, drawn for Devanagari and Latin alike: rounded,
   friendly, and heavy where it needs to be.

   Colour has one job per screen. Home: every aarti card is the same soft
   marigold, so nothing competes with Start aarti. Reader: the title block and
   the line being sung. Text never sits on a pattern, and every pairing below
   meets WCAG AA for its size. */
