/* ==========================================================================
   sections.css  |  kolam mandala, hero card, date chapter, countdown ledger,
   reception ticket, footer. The gallery has its own file; the guest envelope is envelope.css.

   The idea: the page is the invitation card. A pearl card on deep wine, the
   zari karai border at its edges, the kolam drawn on it; further down the
   stationery continues (a ticket, a coupon) and the footer is the card's back.
