/* Design tokens only — global resets removed to avoid overriding

/*
 * Tango Vision Design Tokens — v2
 * Single source of truth for all platform colors, spacing, typography.
 *
 * Brand: AI-native building management OS — digital twins for malls,
 * offices, campuses. Dark-first product. Orange (#F8A324) on deep
 * purple (#5B407F). Montserrat for display/UI, Open Sans Light for
 * long-form body. The wordmark is TANGO.VISION with 0.10em tracking.
 *
 * THREE layers of tokens live here:
 *  1) Brand ramp           --tv-*        (hex; constant across themes)
 *  2) shadcn semantic slots --primary, --background, --border, …
 *     as HSL channels (no hsl() wrapper) consumed via hsl(var(--…)).
 *     These drive every @tv/ui React component and the Tailwind preset.
 *  3) v2 semantic tokens   --bg, --fg, --accent-hover, --hairline,
 *     surface tints, status pairs, focus ring — DIRECT values consumed
 *     by the .tv-* component layer in components.css. These are NOT
 *     HSL channels; reference them bare, e.g. background: var(--bg).
 *
 * Theming: the platform toggles dark mode with the `.dark` class
 * (shadcn / next-themes convention). The v2 handoff toggles with
 * [data-theme]. BOTH are supported — `.dark, [data-theme="dark"]`
 * share one block, `:root, [data-theme="light"]` share the other.
 *
 * See CHANGES.md (handoff) + README for the v1 → v2 migration notes.
 *
 * Note: this file intentionally does NOT @import Google Fonts — a
 * nested @import mid-file violates the CSS spec once bundlers inline
 * stylesheets. Import "@tv/design-tokens/fonts.css" first instead.
