/* Adaptive Runtime — site
   Layout: one reading column (max 72rem) in full-width bands. The header and hero are the
   presentations' navy cover, with the two-tone Georgia headline; the hero's right side is a
   decision record in mono. Below, bands alternate the palette's grounds (névoa, pedra, azul profundo). Palette: Paleta Adaptive Pathways 2026. Type: Roboto Serif for headings, with open
   tracking as in the brand guide, and Barlow for text. All fonts are self-hosted (OFL).
   Single light look, by choice: the brand is light with navy covers. */
