   THE shared signup form. Used on index.html (above the fold), rules.html
   (end of rules) and playgame.html (showdown). Wired up by src/signup.js.

   Anywhere the site asks for a signup it puts the FIELD there, not a link to
   the homepage's #signup anchor. A cross-page anchor made the reader navigate
   away from the thing that just convinced them, and dropped them at the top
   of a page they'd have to re-scan. If you add a fourth surface, copy the
   markup block from rules.html and add this stylesheet + the module — do not
   re-introduce a link to #signup.

   Two palettes: the default is for the cream page background; add
   `signup-on-dark` alongside `signup-section` for a dark backdrop such as the
   showdown overlay.

   ── Why every rule is scoped under `.signup-section` ──
   Host pages style bare elements. rules.html has `.rules-page p` — a class
   PLUS an element, specificity (0,1,1) — which out-specifies a lone
   `.signup-label` (0,1,0) no matter what order the stylesheets load in. That
   rendered the label and the fine-print consent line at full body size the
   first time this component was dropped into the rules page. Scoping to
   `.signup-section .signup-label` (0,2,0) wins on class count and makes the
   component immune to that class of host rule generally, instead of needing a
   per-page patch each time it lands somewhere new. Keep new rules scoped.
