/* ═══════════════════════════════════════════════════════════════════
   REDESIGN LAYER — "al-folio academic" · v2.0.0
   Loaded AFTER style.css. Single-theme refinement of .theme-editorial.
   Aesthetic modelled on the al-folio Jekyll theme (the de-facto
   standard for academic personal sites): white canvas, Roboto Slab
   headings, flat surfaces, hairline rules, one accent for links.
   Remove the <link> to css/redesign.css to fully revert.
   No JS is touched; every selector hooks existing markup/classes.
