/* ── /case-studies/etsy-v2/ — VERSION 2 · RESULTS-FIRST EDITORIAL ─────────
   A genuinely different composition from v1 (Nacim, 2026-08-10 — "yo queria
   algo diferente, una version nueva completamente"). Where v1 stacks
   hero → about → problem/solution toggle → how → results → quote, this
   INVERTS the order and changes the form:
     · The MASTHEAD leads with the outcome — the numbers are the biggest ink
       on the page, a giant hairline stat band, not a footnote at the end.
     · The story unpacks in NUMBERED EDITORIAL CHAPTERS (01–04): a big
       accent numeral + kicker + title in a sticky left rail, an asymmetric
       two-column body on the right, thin rules between chapters.
     · Problem and solution are sequential chapters — the v1 toggle is gone.
     · One full-bleed DARK pull quote gives the light editorial a beat of
       contrast before the CTA.
   Magazine rhythm, brand type + tokens only. All rules scoped
   under .p-case-study-etsy-v2. Same copy as v1, verbatim. */

   Desktop is a two-column stage and stays untouched (≥1024). On phones the
   masthead read logo → facts → title → body → CTA, but the intended reading
   order is logo → title → body → facts → CTA → numbers. The three structural
   wrappers (__top, __split, __copy) collapse to display:contents so their
   children become siblings of __inner's flex column, then `order` sequences
   them. Nothing here touches the desktop grid. */

/* ══════════ MOBILE STICKY BARS — flush to the header (Nacim, 2026-08-12)
   The docked chapter bar showed its 28px rounded corners + a gap under the
   fixed header, so the chapter text scrolled through the seam. On phones the
   bar becomes a flat strip that tucks flush under the header: no top radius,
   no top hairline (the header's own bottom border is the divider), a bottom
   hairline as the only rule it carries, a shorter height, and a dock offset
   matched to the header so nothing peeks above it. */
