/* ---------- wordmark treatments ----------

   Three system-font typographic treatments for the "Fathom" wordmark.
   No web fonts by design — the page makes zero external network requests,
   so Google Fonts is deliberately not used here.

   Option 1 is ACTIVE. To swap: change the class on the <a class="wordmark ...">
   in index.html and thanks.html, then uncomment the matching block below.

   ── Option 1 — Tight weight contrast (ACTIVE) ──────────────────────
   Heavier and more tightly tracked than body text, with a small indigo
   period. Reads as a mark, not a link. Closest to the site's existing feel.

     <a class="wordmark wordmark-option-1" href="#top">Fathom<span
        class="wordmark-dot" aria-hidden="true">.</span></a>

   ── Option 2 — Spaced caps ─────────────────────────────────────────
   Uppercase, small, widely tracked. Quietest and most editorial; echoes
   the .eyebrow treatment used above every h2.

     <a class="wordmark wordmark-option-2" href="#top">Fathom</a>

     .nav .wordmark-option-2 {
       font-size: 0.78rem;
       font-weight: 600;
       letter-spacing: 0.18em;
       text-transform: uppercase;
     }

   ── Option 3 — Serif contrast ──────────────────────────────────────
   System serif against the sans body. Most distinct of the three;
   slightly more traditional / advisory in tone.

     <a class="wordmark wordmark-option-3" href="#top">Fathom</a>

     .nav .wordmark-option-3 {
