/* ==========================================================================
   Aliya's Beauty — booking flow
   --------------------------------------------------------------------------
   /book/, /book/confirmation.php and /in-construction.php.

   Built on the abx design system (css/ds/aliya-ds.css), on the landing
   page's frame (css/landing.css: its tokens, type, top bar, menu and cookie
   notice) and on the shared controls and sheets (css/kit.css). Anything
   added here is a --bk-* token or a .bk-* class.

   Unprefixed classes inside #book (.container, .tab.service, .cta,
   .data-field, .cal-date, .time-slot, .slidePane …) are the markup contract
   of script/script.js, which runs the booking itself. It adds and removes
   them, and injects server-rendered markup that uses them (the calendar, the
   time slots, the sign-in forms, consent forms, the payment pane), so they
   are styled here by those names — always scoped under .bk.

   Written in two layers:

     1. The flow as script.js alone drives it: it shows and hides the step
        containers itself. This is what renders if the page module fails.
     2. html.bk-live — switched on by script/booking/main.js — where the
        module decides which step is on stage and moves between them.

   Sections: 1 Tokens · 2 Frame · 3 Step layout · 4 Controls · 5 Steps
             6 Panes & notices · 7 Other pages · 8 Live layer · 9 Wide screens
             10 Motion preferences
