/*
 * SimplyPages Framework CSS (Core Defaults)
 *
 * This file defines the baseline visual system for framework-generated HTML.
 * Most users should NOT fork this file. Instead, keep this as the stable base
 * and layer project-specific styles with `ShellBuilder.withCustomCss(...)`.
 *
 * Override strategy (recommended):
 * 1) Override `:root` tokens first (colors, spacing, type scale).
 * 2) Add app selectors in your own stylesheet for page/module-specific behavior.
 * 3) Use inline styles in Java only for one-off runtime values.
 *
 * Load order in ShellBuilder:
 * - /css/framework.css
 * - your custom CSS from withCustomCss(...)
 *
 * Matching Java concepts:
 * - ShellBuilder layout: `.main-container`, `.main-sidebar`, `.content-wrapper`
 * - Layout package: `.container`, `.row`, `.col-*`, `.grid-*`
 * - BannerBuilder: `.banner*` family
 * - ContentModule / Rich content wrappers: `.content-module`, `.module-content`
 * - Editing package: styles in "Editing System Styles" section
 */

/* ===== Theme Tokens =====
 * Beginner note:
 * CSS variables are read with var(--token-name). Change values here to retheme
 * large parts of the framework without rewriting component selectors.
