/* E Tech — the design system, built 1:1 from mock B "navy hero" (design/mocks/b.html, PLAN §13) and then
   pushed further: motion everywhere (GPU transforms + opacity only), phone-first, light + dark.
   ORDER MATTERS: base → components → sections → responsive (@media LAST) → motion switches (.still, reduced motion). */
