  Platform: 0.1.1
  Version: 0.1.1
  Created: 2026-04-27
  Updated: 2026-04-27

  Description: Reset and base styles. Box-sizing reset, margin reset,
  font defaults, link defaults, focus-visible defaults. The
  "make every browser behave the same before component styles begin"
  layer.

  Load order: base.css MUST load AFTER tokens.css (uses --bg-base,
  --text-primary, --font-ui, etc.) and BEFORE any component CSS.

  Version History:
    0.1.1 - 2026-04-27 - Session 3 cont'd. Readability floor pass:
                         <small> 12px -> 13px (matches new
                         --font-min-secondary). h6 stays at 12px
                         (display-font small caps, --font-min-display
                         floor). Added a touch-override block that
                         bumps body text 14->15 on coarse pointers.
    0.1.0 - 2026-04-27 - Session 3 initial. Reset extracted from JQiq
                         lines 54-128, RIQ equivalent block, and DZIQ
                         equivalent block (all three apps shared the
                         same reset). Added platform-level
                         focus-visible defaults that views-core.js
                         components depend on.
