/* ============================================================
   JotTower — assets/css/style.css
   One stylesheet for the whole product.

   Palette (fixed by the design brief): paper, ink, muted, line,
   and one amber accent — "rise" — reserved for growth: the
   wordmark's second half, the tower on every shelf card, the
   primary button. Nothing else is amber.

   Type: one family, DM Sans, for everything. Headings and the
   wordmark are set heavier and larger, not in a second face.
   Falls back to the system stack if the font files can't load.

   The signature element is the shelf: cards stand on a plank,
   each carrying a tower whose height is its entry count.
   Everything else stays quiet.
