/* Natalia Tobón Montoya — portfolio styles.
   Direction A · Footnotes. White page on a 12-column grid with hairline rules. Every claim carries a numbered
   footnote with its proof; facts and labels speak in Geist Mono, narrative in Geist. Yellow is only a highlighter.
   Two modes like the live site: dark (#0A0A0A) and light (#F7F7F5). Every page has its own default mode
   (MODE_DEFAULT); opening a page always applies its default, and the toggle only changes the page in view.
   The mode lives on body[data-mode] (not the root), so the viewer's own app theme never overrides it. Desktop: hover reveals (footnotes, cursor-following covers).
   Touch: the same information is always visible (inline covers, tap-to-highlight footnotes). */
