/* ==========================================================================
   PackPilot — website design tokens + stylesheet
   Phase-1 redesign palette (PackPilot_Claude_Code_Website_Redesign_Brief.md).

   Token contract: every colour/space/radius/shadow/type value the markup
   consumes is defined here. No component below should carry a raw hex or a
   magic px that belongs to the system. If a value needs to change site-wide,
   change the token, not the component.

   WCAG 2.2 AA contrast — validated text/background pairs (light theme):
     ink        #1B2030 on bone/surface .......... ~14.6:1  AA/AAA
     ink-2      #3E465D on surface ................ ~8.9:1   AA (body text ok)
     ink-3      #5C6478 on surface ................ ~5.6:1   AA (secondary text)
     ink-4      #7A8195 (decorative/disabled only — NOT for body text)
     clay-deep  #96501F on bone .................. ~5.0:1   AA (links, accent text)
     sage-deep  #2E7D51 on bone .................. ~4.6:1   AA (positive text)
     warn-deep  #7A5A12 on warn-tint ............. ~5.7:1   AA (warning text)
   Base brand/sage/warning hues (clay #C8793D, sage #5CA778, warning #C79735)
   are used for fills, borders, icons and large non-text accents ONLY —
   each is < 4.5:1 on bone, so a *-deep variant carries any real text.
