/* ════════════════════════════════════════════════════════════
   CASE BASE — reglas idénticas en los tres case studies
   ════════════════════════════════════════════════════════════
   Extraído de los <style> inline de kivo/prestio/pivot, donde estaba
   triplicado (73 reglas x 3 = 219 duplicadas).

   ORDEN DE CARGA — IMPORTANTE
   Esta hoja debe ir SIEMPRE la primera, antes de case-theme.css. En el
   markup original estas reglas vivían en un <style> que precedía a los
   <link> de shared/, así que perdían frente a ellas a igualdad de
   especificidad. Cargarla después invertiría ese comportamiento y
   rompería el sitio de formas difíciles de rastrear.

   Lo que NO va aquí: lo propio de cada case (tablas de roles de Kivo,
   barra de proporción de Pivot, acentos de marca) sigue en su <style>
   inline, que se carga después y por tanto puede sobrescribir.
