/* ============================================================================
   Theme integration — gassite.com Divi, all GAS Overview pages
   ----------------------------------------------------------------------------
   These rules reach OUTSIDE .ro-root to adapt the Divi default template. They
   are page-scoped via body.gas-overview-page (added by the mu-plugin's
   body_class filter to any page whose content carries the [gas_overview]
   shortcode) AND this stylesheet only loads on shortcode pages, so they cannot
   affect other pages. This replaces the earlier body.page-id-34777 scoping so
   every overview page (refinery + energy/chemical/environment/catalysis + any
   future page) gets the same adaptations with no per-page-id rule.

   Fixes:
   1. Divi's default template prints the post title as <h1 class="entry-title
      main_title">Refinery</h1> directly inside <article> (no meta wrapper).
      That gave the page TWO H1s (theme title + our shortcode intro H1) and a
      duplicate "Refinery" heading. Hide it so the shortcode intro is the single,
      first H1 (matches approved design 07). The H1 has no wrapping container,
      so display:none removes its height entirely with no empty band left.
   2. The fixed Divi header (#main-header, position:fixed, ~79px tall) would
      overlap the top of the content. Pad #main-content just enough to clear it
      (~90px); the intro's own top padding (.ro-intro, 36px) sits below that, so
      the intro H1 lands a comfortable distance under the menu with no large gap.
   3. Divi's default template reserves a right-sidebar gutter (#left-area is
      ~77% wide), boxing the overview at ~928px inside a 1250px content column.
      This page has no sidebar, so reclaim the full column. width:100% needs
      !important to beat Divi's percentage-width rule.
   4. Divi's style.css sets `h1, h2, h3, h4, h5 { color: #000 !important; }`.
      That !important beats our `.ro-hero h2 { color:#fff }` regardless of
      specificity, rendering the flagship hero heading black-on-navy (unreadable).
      Re-assert white with a page-scoped !important so we win the cascade without
      touching the theme's global H2 color anywhere else. Only the hero H2 is a
      heading element inside the dark panel; all other hero text uses non-heading
      tags and is unaffected.
