 * The availability calendar of the customer-journey redesign.
 *
 * COLOR MEANS AVAILABLE (inverted 2026-08-11 on Jeroen's feedback -- filled
 * tiles for occupancy read counter-intuitive). Each apartment has its own
 * tint from the brand family: the house is the footer mauve, the studio a
 * Piemonte sage. Top-left triangle = house, bottom-right = studio. Under a
 * single-apartment filter the whole tile carries that apartment's tint when
 * it is free; an occupied day is pale and quiet.
