/* ==========================================================================
   Endless Hybrids — Base  (v1.1.0)
   Reset + base element styles (reading semantic tokens) + motion primitives.
   Load AFTER tokens.css + themes.css, BEFORE components.css.
   Intentionally light: components do the heavy lifting; this just makes raw
   HTML look on-brand and provides the shared .eh-reveal scroll animation.
   v1.1.0: strong=heading/600, text-wrap balance/pretty, p max-width 70ch,
   :focus-visible red ring. (Components with their own strong/p rules override
   these — e.g. the navy Banner keeps its cream strong.)
