/* cb-diff.css: /cross-border-divorce/ section 5: the statement (Statement.astro, cbs-) and the five
   differences carousel (Differences.astro, .cb-diff). Motion: cb-statement.js (the statement only; the
   carousel is the shared site.js [data-carousel] engine).

   STATEMENT (the 離婚手續 s3 phone recipe at every width, dp-stage.css lines 200-290):
   DEFAULT = FINAL STATE: a green band with the statement, every character shown, no pin. Armed
   (html[data-cbs-armed], cb-statement.js, motion allowed): the pin is RUNWAY screens tall (written by the JS),
   the stage is sticky 100vh, the characters light one by one from ONE number (--cbs-s, px travelled into
   the reveal) and the next block, .cb-diff, is pulled up one screen (margin-top: -1 screen) and scrolls OVER
   the still-pinned stage as an opaque cover (z-index 2, paper ground). No opacity hand-off, so there is no
   frame where both the statement and the carousel are gone (the s5 blank-viewport row).

   DIFFERENCES: a copy of public/components/mt-s3.css (贍養費 s3) re-scoped .mt-orders -> .cb-diff and
   [data-carousel-tabs="orders"] -> [data-carousel-tabs="cbdiff"]; plus the 香港 | 內地 compare cells and the
   light switch into s6 (dp-consultant.css's .dpc-ground shows through this section once it is on). */
