/* =========================================================
   Brad Hakes — writing site (the catchall notebook)
   Companion to the curated substack "Imagination Compact"

   Design system:
     - Warm paper-tone palette (light & dark modes both warm)
     - Serif body & titles (Iowan / Palatino stack)
     - System sans-serif for the contact card
     - Mono for dates
     - Single column, ~420px, centered
     - Hover-reveal dates on desktop; always-visible dates on mobile
     - Sun/moon toggle anchored to the column's top-right corner,
       optically centered on the corner (translate -50%, +50%)
