   Koltype site.css
   Shared styles for koltype.com. Plain CSS, no build step, no web fonts.

   COMPONENT REFERENCE (for the login, account and desktop-auth pages)
   ---------------------------------------------------------------------
   Page skeleton
     <link rel="stylesheet" href="/css/site.css">
     <script src="/js/site.js"></script>  in <head>, no defer. It applies the
     saved theme before first paint, then wires the nav toggle and theme button.
     Copy the <header class="site-header"> and <footer class="site-footer">
     markup from any marketing page. <main id="main" tabindex="-1"> is the
     skip-link target. Never use inline <script> or on* attributes (CSP).

   Layout
     .container          centered column, max 1200px, responsive side gutters
     .container-narrow   same, max 760px (forms, legal text)

     .cluster            wrapping row with gap (buttons, badges)
     .grid .grid-2 .grid-3   responsive grids; collapse on small screens
     .shell-center       fills the viewport under the header, centers a child
     .panel              width-limited card for auth forms (max 440px)
                         usage: <div class="shell-center"><div class="card panel">...</div></div>

   Type
     h1 to h4 (or .h1 to .h4), .lead, .muted, .small, .eyebrow (mono label)
     .prose              long-form text (headings, lists, tables, links)
     kbd or .kbd         keycap, e.g. <kbd>Ctrl</kbd>

   Buttons (on <a> or <button>)

       .btn-primary      signal coral, the main action (one per view)
       .btn-secondary    outlined
       .btn-ink          highest contrast (ink in light mode, white in dark)
       .btn-ghost        text-like
     sizes   .btn-sm  .btn-lg   width  .btn-block
     states  :disabled or [aria-disabled="true"]; [aria-busy="true"] shows a spinner

   Cards
     .card               surface, border, radius, padding
     .card-raised        adds a shadow
     .card-accent        signal coral top edge

   Forms
     .field              wrapper: label, control, then help or error text
     .label .input .select .textarea .help .field-error
     .input-code         one-time code entry (mono, letter-spaced, centered)
     .check              <label class="check"><input type="checkbox"> Text</label>
     invalid             aria-invalid="true" on the control, plus .field-error text
                         linked with aria-describedby

   Alerts   .alert + .alert-info | .alert-success | .alert-warning | .alert-error
            use role="status" for info/success and role="alert" for errors
   Badges   .badge + .badge-signal | .badge-success | .badge-warning | .badge-muted
   Tables   <div class="table-wrap"><table class="table">...</table></div>
            the wrapper scrolls sideways on small screens
   Misc     .divider  .sr-only  .spinner  .skip-link  .center

   Tokens: every color, radius, shadow and font is a custom property on :root.
   Theme: follows the OS via prefers-color-scheme; <html data-theme="light">
   or data-theme="dark" overrides it (site.js stores the choice).
