/* ==========================================================================
   INOX AIR — design tokens
   Palette: INOX AIR blue — brand blue for the dark sections (top bar,
   hero, footer, quote box) and as the main accent — brushed grey,
   blueprint paper.
   Type: Inter (variable, optical sizing) for everything — soft, clean
   Apple-style letterforms; sentence-case headings, tabular figures in data
   ========================================================================== */

/* Self-hosted variable webfont (no external Google Fonts request — keeps the
   site self-contained and usable offline). Inter, with the weight and
   optical-size axes: large headings automatically get the tighter "Display"
   letterforms, small text the open "Text" ones. */
