/**
 * ============================================================================
 * THE APPRAISER'S GRIMOIRE - Main Theme Stylesheet
 * ============================================================================
 *
 * Visual Inspiration: Classic fantasy illustration art in the style of the
 * Brothers Hildebrandt, Ted Nasmith, and Greg Hildebrandt. The aesthetic
 * evokes illuminated manuscripts, wizard's studies, and twilight journeys
 * through mystical landscapes.
 *
 * Key Design Principles:
 *   - Painterly quality with rich, detailed oil painting aesthetic
 *   - Twilight atmosphere with deep blue evening skies
 *   - Warm golden accents against cool blues for high contrast
 *   - Mystical serenity with a contemplative, journey-focused mood
 *   - Fantasy landscape elements: stone archways, winding paths, starry skies
 *
