/* ===========================================================================
   aiquery.dev — site.css  (Phase 7 frontend modernization)
   ---------------------------------------------------------------------------
   The single site-wide design system. No frameworks, no external fonts.

   CONTRACTS HONOURED BY THIS FILE
   1. Chrome class names consumed by the S3/TT templates:
        .container .site-header .site-header-inner .brand .brand-mark
        .brand-name .brand-tld .site-nav .nav-link .auth-area
        .site-main .card .engine-card .engine-content
        .site-footer .site-footer-inner .footer-copy .footer-note
        .breadcrumb .breadcrumb-sep .breadcrumb-here
        .page-header .page-heading .page-title .page-title-suffix .page-lede
        .page-tabs .tab .is-active
        .hero .home-card .about-card .section-title .section-note .empty-note
        .link-grid / .home-links (home page raw <a> link lists)
        .login-wrap .login-card .login-sub .form-field .form-message
        .btn .btn-primary .btn-block (.login-form is a marker, no rules)
   2. ENGINE-RENDERED markup is golden/untouchable and is styled purely from
      the outside, by selector only:
        - input_form():  <div style="background-color: #F0F0F8;"><form>
                           <input type=text name=sdql|pyql ...> <BR>
                           <input type=submit name=submit ...>
        - result tables: <table id='pyql_id' class='pyql_class'> (query pages,
          one PER GROUP — ids repeat, so ONLY class selectors are used) and
          <table id='sdql' class='sdql'> (trends/bar queries), each with
          <thead>/<tbody>.  ResultDict.html() emits a <b>group-key</b> label
          immediately before each group table.
        - right_header(): table-based mini login form (form action="/login")
          injected raw into .auth-area by sdb.tt.
   3. Custom properties read by Admin/admin.css (bare names first, then the
      --color-* spelling) — both spellings are defined below:
        --bg --surface --border --border-soft --text --text-soft --accent
        --accent-dark --danger --danger-bg --success --success-bg --warning
        --warning-bg --muted-bg --font-sans --font-mono
   4. Hooks used by JS/tablesort.js (th[aria-sort], table[data-sort-enhanced])
      and JS/export.js (.export-actions, .export-btn).
