/* Cheese — shared Signup/Login visual system
   Used by pages/signup/ and pages/login/, which are near-identical in shape
   (a centred glass card holding a small form) and differ only in copy and
   field list — the same reasoning that already factored out board-layout.css
   and nav.css for pages sharing structure. Load this file BEFORE the page's
   own style.css so page-specific rules can still override where needed.

   Visual language: glassmorphism, matching the home page hero and the left
   nav — NOT the flat-black/sharp-corner language of cheese-dialogs.css. That
   language is reserved for transient system UI (confirm/prompt popups); a
   Signup/Login page is a full destination someone lands on, not an
   interruption.

   No functionality lives here or in these pages' HTML — no Clerk, no real
   submit handling. That is intentionally deferred (see the plan). Forms use
   `onsubmit="return false"` purely so clicking the button doesn't trigger a
   real (broken) GET-to-self navigation with form fields dumped into the URL
   — that is a side effect of using semantic <form> markup with no handler,
   not a feature. */
