/*
 * Business Stamp Diagnostic – Stylesheet
 * OPTION 2: SOFT PROFESSIONAL
 *
 * Gentle, approachable design with soft blues, rounded corners, and subtle shadows.
 * Professional but friendly atmosphere.
 *
 * ARCHITECTURE NOTE:
 * This file is the AUTHORITATIVE source for all visual formatting.
 * It is copied to dist/css/style.css during build.
 *
 * Separation of concerns:
 * - Content:    YAML + Markdown in content/
 * - Structure:  HTML templates in build.py
 * - Formatting: THIS FILE (CSS only)
 * - Behavior:   stamps-engine.js (state, events, data)
 *
 * The stamps-engine.js renders HTML with class names; this file defines
 * how those classes look. The engine should NEVER contain style definitions.
