/* PocoLocoLife — Foundation Stylesheet
   ----------------------------------------------------------------------------
   Design foundations ported from the OneTribe web design system:
   Poppins type scale, 4px spacing scale, radii, shadows, transitions, and the
   ds- component layer (buttons, cards, badges, headings, container/section).

   COLOR / BRAND IS DEFERRED. Color tokens live in head/variables.html so they
   can be themed in a later design session. The accent (--color-primary) is a
   neutral ink placeholder for now — swap it there, not here.

   Coexists with Tailwind (CDN). Tailwind utilities still work; ds- classes are
   additive and use the ds- prefix to avoid collisions.
