/* ============================================================
   STANDALONE PLATFORM SECTION — interior pages
   ============================================================

   The platform map rendered on its own, below a page title, rather
   than as numbered panel 02 on the homepage. Both render the same
   _PlatformMap.cshtml partial in Umbraco, so there is one copy of
   the markup.

   ⚠️ .platform__inner STAYS IN THE MARKUP EVEN THOUGH ITS GRID IS
      TURNED OFF BELOW. It is where --platform-shift is declared
      (3.75rem at >=992px, 8.75rem at >=1460px), and every rule
      downstream reads that custom property: the margin-inline /
      padding-inline pair on this element, and the evidence block's
      own shift. Delete the wrapper and the map narrows and the
      hairlines stop lining up with the rest of the page.

   ⚠️ .platform--a IS ALSO REQUIRED ON THE SECTION. It collapses the
      three-column evidence grid (stepper · map · spacer) to one
      centred column, zeroes the map's translateX, and spans the
      evidence 1 / -1 so the hub sits on the page's true centre
      rather than 2rem right of it. Misha, 2026-08-31.

   What --bare removes is the PANEL: the hanging number, the rule
   above it, and the grid that placed them. */
.platform--bare {
    padding-block: clamp(2rem, 4vw, 3rem) clamp(2.5rem, 5vw, 4rem);
}

/* display: block, not grid — there is no number and no heading to
   place. .platform--a .platform__evidence sets grid-column: 1 / -1,
   which simply goes inert here; a block child fills the width anyway. */

    display: block;
    border-top: 0;
    padding-top: 0;
