   Palette pulled from the product: deep navy shell, teal action gradient,
   amber promo accent. Space Grotesk carries headings (a technical,
   geometric voice for a payments brand); Inter carries body copy;
   IBM Plex Mono is reserved for anything that is literally a number —
   amounts, meter numbers, transaction IDs, exchange rates.
