/* ---------- Hero ---------- */
/*
  Misty Huangshan-style peaks and pines, set the same way as /tea-ceremony's
  hero so the two pages read as one system: the photo never sits under the
  text. Mobile: photo as a banner at its native ratio, text below on Paper.
  Desktop (1025px+): text on plain Paper at left, photo in the right-hand
  columns.

  The source is small (650px wide), so it is shown no wider than ~2/3 of the
  page width and toned down — desaturated and lifted — which
  also lets the blues sit quietly beside the cream and ink type.

  Soft edges, top and bottom only (the sides stay sharp, 2026-10-21):
  ::before is a blurred copy, ::after the sharp copy fading into it, and
  the block fades into Paper over --hero-feather (5%) at the bottom and
  --hero-feather-top (10%) at the top, so the sky melts away more.
