/* Veya Digital — case-study chapter opener. Shared by every /work/ page
   and the homepage. Each chapter is a normal, stacked block in document
   flow — no scroll pin, no position:fixed, no scrub. It fades up into
   place as it's scrolled to, then stays put; the next chapter does the
   same below it. Distinct copy and per-page chapter count, same rhythm. */
