/*
Purpose: page-level rules for the company routes (/about/, /news/) on top of the shared shell. The portfolio, sciences, surfaces and architecture routes are retired, and their rules left with them (audit CODE-09).
Governance scope: founder block, Roman-numbered principles, changelog list, and the restyle of pinned legacy readouts.
Dependencies: assets/shell.css tokens and components (linked first) and the rules these routes used from assets/styles.css, copied in section 0 with the alias tokens (audit R1-024); the routes no longer link styles.css.
Invariants: no tokens or fonts beyond the copied aliases, no viewport units in font sizes, no negative tracking, 12px floor, 44px targets, nothing hidden until scrolled.
*/

/* ==========================================================================
   0. Rules copied from assets/styles.css for /about/ and /news/ (audit R1-024):
      the selector-list members these routes can match, the focus ring, the alias
      tokens and their breakpoint re-sets, in source order, so the cascade is
      unchanged now that the routes no longer link that sheet. Keep them in step
      with assets/styles.css.
