   QUIMERA — Responsive layer + multi-page nav
   Loaded AFTER site.css / imagery.css so it can refine layout.
   Desktop-first: base rules define desktop; media queries restack.
   Grid layouts that used to be inline now live here as classes
   (.q-svc-row, .q-work-row, .q-persp-grid, .q-manifesto-grid) so
   breakpoints can reach them.
