/* Philip Eyram Djokoto, portfolio

   Design system (dark only)
   Type      Hanken Grotesk 400/500/600 for body text. Geist 900 for the hero headline (28 to 84px) and
             Geist 800 for section headings (26 to 32px), project titles (20 to 30px) and skill tabs.
             Archivo Black for the wordmark. DM Mono 400/500 for indices, meta, labels and tags (11 to 13px).
             Body 17px/1.6, secondary text 14 to 15px.
   Color     Every color is a token below. No blues or purples, no gradients, no white backgrounds.
   Spacing   Steps of 8, 12, 16, 24, 32, 48 and 96px, with 2px adjustments for optical alignment.
   Shape     Radius 4px on tiles, buttons and images, 0 on rules. Borders 1px. No shadows.
   Layout    12-column grid, 1200px max. Each section: label column (3) and body (9), with a 40px
             gutter above 900px. Magazine, not SaaS. */
