/* Koubit Consulting — page styles.
   Tokens come from css/tokens/*.css; this file holds layout and components.

   Conformance notes:
   - Colour, typography, radius, border-width and motion all resolve through
     design-system tokens. Semantic aliases (--bg-page, --brand-primary,
     --border-strong) are preferred over raw palette steps.
   - Font sizes use the token scale where the design lands on it exactly
     (15/17/20/13px). The design also uses intermediate sizes (14.5, 15.5,
     16.5, 19, 22, 30, 34, 36, 38, 54px) that the shared scale does not
     define; those stay literal rather than being snapped to a nearby token,
     which would change the rendered design.
   - Layout spacing likewise stays literal: the design's rhythm
     (18/22/26/28/30/44/72/88px) does not follow the --space-* scale
     (4/8/12/16/24/32/48/64/96/128px). Forcing it would alter the layout. */

  --page-gutter: 40px;
  --container-content: 1160px;          /* design's content column; note the
                                           shared --container-max is 1180px,
                                           which this page deliberately does
                                           not use — 1160px is what the design
                                           source measures. */
