   Barbara Pinete — Portfolio
   v2 — correcciones:
   1. sin tagline de disculpa
   2. grid parejo, tiles consistentes, escala a 5+ proyectos
   3. nombre de proyecto oculto hasta hover
   4. headline de concepto + contexto por proyecto
   5. paleta sin cambios (color real de las fotos, no B&N forzado)
   Un solo sistema tipográfico (sans), sin serif decorativo.

   Structure borrowed directly from Alejandra's project pages:

   content column (concept headline, context, then the gallery).
   No image is ever force-cropped — each keeps its own ratio,
   so nothing gets cut down to nothing. */
