/* ============================================================
   The Personal Challenge — scrapbook / journal-page aesthetic
   Same navy + pastel world as AI Human Bingo and 3 Commitments: a
   dark backdrop holds a tilted, taped-down paper card. Two text
   contexts to keep straight throughout this file:
     - directly on the navy page (body, header, footer, toast) → light
       text: --paper or --muted
     - on the light paper card (the form itself) → dark text: --ink,
       --accent-ink or --muted-2, and rule lines use --paper-line
   Palette (identical tokens/values to the root stylesheet)
     --ink #3d4a63 (navy, doubles as dark text-on-paper)
     --paper #faf5ea (card stock)      --muted-2 #6b6459 (text-on-paper, secondary)
     --accent #9dbb8a (sage)  --coral #d99aa6 (dusty pink)  --sky #a9c6de (powder)
     --cream #e6d98f  --accent-ink #232c3e (dark text-on-pastel-fill)
   Type: Permanent Marker (handwriting) / Work Sans (body) / IBM Plex Mono (meta)
