/* =========================================================
   ほの — 目を休めるリズム / a place to rest the eyes
   Direction: the screen's blue light (tension) gives way to a
   restful green space lit by one faint warm light (ほの = a
   faint glow). The whole site is the "far green" you look at
   to rest your eyes — the real 20-20-20 eye-care guideline made
   into an environment. The day's screen-time travels as an arc:
   朝の光 → 昼の集中 → 夕の減光 → 夜の就寝.

   Signature: 「目休めのリズム」— a three-beat rest clock reading
   20分 / 20秒 / 20フィート, that softly dims the cool screen-blue
   into warm light once per cycle. A rhythm, not a level filling up.

   Palette — restful green ground (~135°, yellow-leaning) + a small
   warm clay glow (ほの) + cool slate confined to the signature.
   Deliberately NOT:
     · cream + mincho + terracotta            (AI default #1)
     · near-black + single acid accent        (AI default #2)
     · broadsheet hairline columns            (AI default #3)
     · purple / periwinkle                    (うるか・hsp)
     · honey-amber identity / dark warm room  (site18 / site01)
     · coral / pink                           (site16 ぽかぽか手帖)
     · teal / cyan (~190°)                     (site17 ひんやり手帖)
     · 明朝 / 丸ゴシック / 手書き display       (sister faces)
