/* Krindel technical brief — paper layer (Website Phase A demo,
   docs/superpowers/specs/2026-07-04-paper-presentation-design.md).
   Composes on styles.css: reuses --paper/--surface/--ink/--muted/--rule/
   --accent, the mono/sans stacks, .kicker, .spec-rows/.spec-row,
   .table-scroll, .code-block, .steps. Adds only what a research-paper
   layout needs on top: numbered section rhythm, a two-column abstract,
   figure + mono caption, a results table skin, a pending-slot marker,
   and a print stylesheet. No new colors, no new fonts. */
