   Luna · Ciklusnaptár — "the quiet cycle calendar for two"
   The design system of the sister sites (Kedves · Curio): a dark, premium,
   softly-lit scene where every accent derives from a single hue --h — here the
   hue follows the CURRENT CYCLE PHASE (rose → mint → gold → violet).
   Bilingual (HU/EN). No build step, no framework — HTML, CSS and vanilla JS.
   All data lives on the visitor's device.
