/* Stable Genius — stablegenius.si
 *
 * Typography follows the logic of Apple's product pages (measured from apple.com production CSS):
 *  - One idea per viewport, set very large. Scale contrast does the work that colour and weight do elsewhere:
 *    a 96px headline over 21px copy is a ~4.5:1 ratio, so the eye lands on the claim first, the proof second.
 *  - Display sizes use tight leading (1.04–1.07) and slightly negative tracking; text sizes open up (1.38–1.47).
 *  - Weight stays restrained: 600 for every headline, 400 for copy. No 700/800 shouting.
 *  - Emphasis inside copy is brightness, not boldness: paragraphs sit in grey, and the one sentence that matters
 *    is lifted to full white (or near-black on light). The reader can skim the bright phrases and get the story.
 *  - Sizes step at Apple's breakpoints (1068px, 734px) rather than scaling fluidly, so each layout is tuned.
 * SF Pro is used where the OS provides it; everywhere else, self-hosted Inter (variable, optical sizes).
