/* ================================================================
   Estimating-portfolio project cards (.pcard) - v2
   Loads AFTER styles.css + projects-uplift.css.

   Token rules (see the two live token defects in styles.css):
   - never use var(--text-body) for colour; it resolves to 1rem in
     light theme and the declaration is dropped. Use the local
     --pc-* tokens below, declared on :root so they are always in scope.
   - never use var(--space-7); it only exists via projects-uplift.css.
   - the site is mono-teal: the per-sector colours in styles.css are
     overridden to #2bcbba, so sector is carried by label + icon, not hue.
   - light-theme teal text is #086a5f (AA 6.5:1 on white); bright
     #2bcbba only in dark theme and on the always-dark page header.
