/* =========================================================
   うるか — 湿度計 / the humidity instrument
   Direction: dryness is measurable (RH%). うるおい is water in
   the air. The whole site is an environment "filling" with
   moisture across a day's arc (手元→髪→衣類→空気→就寝).
   Signature: a humidity gauge that is BOTH the hero and the
   scroll navigation — one instrument, two placements.

   Palette: a two-temperature world — outside dry & cold
   (periwinkle / misted violet-blue) vs inside warm & moist
   (honey / amber room-light). Honey is the identity color,
   absent from both sister sites.
   Deliberately NOT:
     · cream + mincho + terracotta (AI default #1 / old うるか)
     · near-black + single acid accent (AI default #2)
     · broadsheet hairline columns (AI default #3)
     · coral/pink + Zen Maru rounded  (site16 ぽかぽか手帖)
     · teal/cyan + M PLUS rounded     (site17 ひんやり手帖)
