   2. LAYOUT CONTAINERS
   ========================================================================== */

/**
 * Content and Container
 * Canonical definition for page width constraint.
 * These classes center content and apply consistent padding.
 *
 * IMPORTANT: Horizontal padding uses --content-padding-x which is responsive
 * (defined in 00-tokens.css with breakpoints). Component CSS should NOT override
 * padding-left/right directly - instead override the variable if needed:
 *
 *   .special-panel .content { --content-padding-x: 100px; }
