/*
 * VELYX Brand Theme 2.0
 * ============================================================
 * Digital theme based on the approved VELYX brand palette.
 *
 * Intended for:
 * - ASP.NET Core
 * - ASP.NET MVC
 * - Razor Pages
 * - Blazor
 * - .NET web applications
 * - Standard HTML websites
 *
 * Brand principles:
 * - Midnight communicates authority.
 * - Architectural Navy communicates architecture.
 * - Intelligence Blue communicates technology.
 * - Mineral Teal communicates transformation.
 * - Architecture Mist communicates structure and context.
 * - Graphite communicates information.
 * - Architectural White communicates clarity.
 *
 * Accessibility:
 * - Midnight on Architectural White: WCAG AAA
 * - Graphite on Architectural White: WCAG AAA
 * - Intelligence Blue on Architectural White: WCAG AA
 * - Mineral Teal on Midnight: WCAG AA
 *
 * Important:
 * Mineral Teal must not be used for normal text on light surfaces.
 * Gradients are expressive brand treatments, not core logo colors.
