   Layout
   ========================================================================== */

/*
 * Astra Full-Width Override
 * -------------------------
 * Astra's "Boxed" site layout wraps page content inside .ast-container (or
 * similar wrappers) that carry a max-width and horizontal padding, causing
 * section backgrounds to cut off at hard edges instead of spanning the
 * full viewport width.
 *
 * The PHP filters in inc/landing-page.php (astra_site_layout,
 * astra_page_layout) are the primary fix. These CSS rules are a belt-and-
 * suspenders fallback that handles any residual constraint Astra may inject
 * via .ast-container, .entry-content, or .site-content regardless of the
 * Astra version or active addons.
 *
 * Pattern: section backgrounds go edge-to-edge (100vw); the inner
 * .breatheazy-container constrains content to 1200 px centered.
 */

/* Remove max-width and padding from Astra's content wrappers when the
   landing page template is active. The body class breatheazy-landing-page
   is added by inc/landing-page.php via the body_class filter. */
.breatheazy-landing-page #content,
.breatheazy-landing-page .site-content,
.breatheazy-landing-page .ast-container,
.breatheazy-landing-page #primary,

/* The .breatheazy-landing wrapper itself must stretch to the full viewport.
   width: 100vw + negative margin technique is not needed here because the

/*
 * Section Full-Width Pattern
 * --------------------------
 * Every direct <section> child of .breatheazy-landing is implicitly 100%
 * wide because block elements stretch to fill their container. The
 * backgrounds painted on those sections therefore span the full viewport
 * once the ancestor containers are reset above.
 *
 * If a section still clips (e.g. Astra injects a wrapper with overflow:hidden),
 * the width: 100vw + negative horizontal margin technique below can be
 * applied directly to individual sections as a last resort. It is NOT used
 * by default because it causes a horizontal scrollbar unless the nearest
 * overflow:hidden ancestor is the viewport itself.
