Sub-item of #910 EPIC mobile-first refactor (Elazar directive, all 3 apps): Mars is desktop-CSS-with-patches, not mobile-first. Staged base-up rework. Stage0 foundation (44px tap floor + search/form fixes, mobile-only media blocks, desktop density unchanged); Stage1 DataTable mobile card mode (fixes /practicas + /docentes); Stage2 /mi-cursada; Stage3 /practicas/nueva form (+tooth-selector tap targets, +undefined .conducto-* classes latent bug); Stage4 filter-bar accordion; Stage5 practica detail (/practicas/[id]+/mi-cursada/[id]: info-bar, changelog, comentarios, review-form, image-viewer pinch-zoom currently broken on mobile); Stage6 secondary (soporte thread, notificaciones, perfil, postgrado-progression). Order 0>1>2>3>5>4>6. Owners: coder-mars 0/3/5, audit-mars-ca 1/6. Held on proxy-mars BEFORE baseline (Elazar launching). Admin wide-tables=P3 tail/defer. · mars
