/* ══════════════════════════════════════════════════════════════════
   FitLog · landing page

   Design system: the product is a LOG, so the page borrows from a
   real logbook, not a SaaS template. Ruled hairlines instead of
   gradient glow, a ledger card instead of a phone screenshot, and
   sharp corners because the app itself has none rounded off.

   Color:  ink (near-black, warm) and paper (warm cream, for the two
           printed surfaces). Two accents, each with a fixed meaning:
           ember is the streak, violet is Pro.
   Type:   Big Shoulders Display for the wordmark and big numerals,
           Work Sans for reading, IBM Plex Mono for anything that is
           genuinely tabular. A ledger device, not a hacker one.
   Layout: asymmetric, left-set, ruled like a page in a logbook.

   * A colour that means something is worth more than a colour that is
