  /* ── Typography ─────────────────────────────────────────────────────
   *
   * Type system uses two Barlow variants:
   *
   *   DISPLAY / HEADINGS  → Barlow Semi Condensed
   *     Narrower letterforms give headings a distinctive editorial feel.
   *     Use MEDIUM (500) or SEMIBOLD (600) — never 700/800 which are
   *     too heavy at large sizes with this condensed cut.
   *
   *   BODY / UI           → Barlow (regular width)
   *     Comfortable reading at small sizes. Use 400 for body,
   *     500–600 for emphasis and buttons, 700 only for data/counters.
   *
   * Weight mapping (what's loaded):
   *   Semi Condensed:  300 · 400 · 500 · 600 · 800
   *   Barlow:          300 · 400 · 500 · 600 · 700 · 800
   *
   * Hierarchy is achieved through SIZE + SPACING, not raw weight.
   * Bigger text → lighter weight. Smaller text → heavier weight.
   *

   * Usage guide:
   *   --sfl-weight-light (300)     → Decorative large text, background text
   *   --sfl-weight-regular (400)   → Body copy, descriptions
   *   --sfl-weight-medium (500)    → Card titles, nav items, small headings
   *   --sfl-weight-semibold (600)  → Section headings, hero headlines, buttons, emphasis
   *   --sfl-weight-bold (700)      → Counters/data figures (Semi Condensed like all headings)
   *
   * Rule of thumb: if the font-size is > 2xl, use semibold (600) max.
