/* ═══════════════════════════════════════════════════════════════════════════
   @nobul/ui — component CSS (v2026.9.0) — Phase 2: full component library
   (+ 2026.9.0: header icon-bar, .btn-table-text, table typography standard)

   Phase 1 shipped the skeleton sections ui.js renders (toast, dialog,
   shortcut help, skeletons, empty states, field errors, view states) —
   those sections are UNCHANGED below (two hardcoded toast colours were
   swapped for the identical-valued tokens; zero visual change).

   Phase 2 adds the component layer, all token-driven:
     • Buttons — the full 9-level hierarchy per .docs/nobul-button-hierarchy.md
       (+ .option-btn selectable-choice pattern)
     • Badges — the tone system per .docs/nobul-badge-standards.md
       (success/warning/danger/info/neutral; NO domain classes)
     • Forms — .form-field/.form-label/.form-control, the locked --cb-size
       checkbox (24px default, .checkbox-sm 18px dense), toggle switch
     • Tables — .table shell, .table-wrap, zebra/dense options, focusable
       rows, opt-in .table-cards-mobile responsive transform (from people)
     • Cards, filter bar, page header

   Accent colour: components resolve their accent through
   var(--primary, var(--brand-accent)) so apps that already define --primary
   keep their exact colour, and pure-package consumers pick up the per-app
   overrides/<app>.css accent.

   Requires tokens.css (or an app stylesheet defining the same custom
   properties) to be loaded first. Everything here is additive — apps whose
   own CSS already styles a class identically simply win on specificity/order.

/* ── Toast (engine v2 — reference visual) ───────────────────────────────────
   Solid saturated type fill + white text + white circular icon badge.
   Deliberately theme-invariant (same decision as v1): no dark-mode rules.
   The type fill flows through the private --_toast-fill custom property so
   the badge glyph picks up the same hue (--cb-size pattern).
   The --warn token only reaches 3.19:1 under white text, so the warning
   fill uses the component token --toast-warn — defaulting to the shared
   amber-700 strong-warning token (5.02:1 with white; WCAG AA). Apps may
   override the custom property.                                           */

/* ===== Tooltip ==========================================================
   The hover/focus tooltip standard (lifted from the safety dashboard
   pills). Two tiers, one visual language:

   1. RICH panel — structured content (head row, uppercase section labels,
      message blocks). Markup via NobulUI.tooltip():
        <span class="nui-tip" tabindex="0">TRIGGER
          <span class="nui-tip-panel" role="tooltip">
            <span class="nui-tip-head"><span>TITLE</span>[badge]</span>
            <span class="nui-tip-label">SECTION</span>
            <span class="nui-tip-message">text</span>
          </span>
        </span>

   2. SIMPLE attribute tip — one-line hints via data-tip="text" on any
      element (replaces native title= tooltips). Same panel styling via
      ::after.

   Both show on hover AND keyboard focus, and are tokenised/dark-correct.
   NobulUI.initTooltips() flips either tier away from viewport edges via
   data-tip-place="below" / data-tip-align="left|right". */
