/*
 * Homepage section 02: the five booking steps beside a day in the Inboxxit
 * calendar where the hero's 2:30 AC diagnostic lands.
 *
 * Static by default (reduced motion, print): every step lit, 2:30 booked,
 * 4:15 free. Only when motion is allowed does it replay on one 12 s loop:
 *
 *   0-18%   step 1  a scan line reads the day
 *   18%     step 2  2:30 and 4:15 are marked "Offered in the chat"
 *   40%     step 3  "2:30 works." appears on the 2:30 slot
 *   55%     step 4  2:30 shows "Re-checking it's still free"
 *   70%     step 5  2:30 becomes the booked AC diagnostic; 4:15 stays free
 *   97%             everything resets
 *
 * Steps light up cumulatively, like a checklist. Pure CSS, no script.
