/* ============================================================
   Angel Houseboats — design tokens
   Concept: the business sells two things — a day and a night.
   The whole site is built from that duality: bands of page
   alternate between a paddy-field cream "day" and a backwater
   dusk-teal "night", stitched together by a ripple divider and
   the arched profile of a kettuvallam (thatched houseboat) roof,
   which recurs as the one signature shape throughout.
