/* Milestone 2b: /about/'s markup carries `.interior-principles` together
   with `.wrap` on the same element (<div class="wrap interior-principles">).
   `.wrap`'s own `margin: 0 auto` shorthand (site-shell.css) and this file's
   `.interior-principles { margin-top: 48px }` rule above have equal
   specificity (0,1,0 each); now that site-shell.css deliberately loads
   LAST (binding decision 1, so no page-composition sheet can win protected
   shell properties by source order), `.wrap`'s shorthand would otherwise
   win this unrelated, unprotected margin-top and silently zero out the
   48px gap above the principles grid — verified via getComputedStyle
   before/after this rule was added. This selector only raises specificity
   (0,2,0) to restore the pre-existing 48px value regardless of stylesheet
   order; it does not change what any route currently renders. */
