/* ============================================================
   LIFE IN SOFT COLORS - DESIGN SYSTEM
   Archetype : Sun-print / Cyanotype Album
   Fonts     : Arapey (display, pulled lines, annotations) / Kumbh Sans (body, UI)
   Palette   : cyanotype indigo #2E4A6B . rag paper #F2EFE7 . dusty rose #B98A8A

   Signature devices (this site only):
     1. Exposure scale  - six discrete solid blocks stepping light to dark.
        Replaces the uppercase tracking eyebrow everywhere.
     2. Cyanotype duotone - index imagery bleached to high-key grey, multiplied
        over indigo, highlights screened back. Content imagery stays full colour.
     3. Brush deckle edge - clip-path on hero image and dark bands.
     4. Annotation line - Arapey italic metadata, pipe separated.

   Hard rules: radius 0 everywhere. Zero box-shadow. Zero gradient backgrounds.
   Zero em dash. Motion dial 1 (CSS hover + native scroll progress only).
