/* =========================================
   1. Top Layer (Holds Sidebar & Content Frame in the SAME layer)
   ========================================= */
/* QUO-37 Mechanism 2: the scroll-driven four-app sequence pins this section.

   WHY THE PIN LIVES HERE AND NOT IN views/home.html, which is where QUO-37
   originally specced it. Measured on 487adea, not assumed: a position:sticky
   element inside the hero markup DOES NOT PIN AT ALL - it sat at top 69px at
   scroll 0 and top -631px at scroll 700, i.e. it scrolled away exactly like a
   static element. overflow:hidden does not only clip, it creates a SCROLL
   CONTAINER, and sticky pins to its nearest scrolling ancestor. #viewMount never
   scrolls (scrollHeight === clientHeight), so the sticky had zero scroll range
   and silently degraded to static - no error, no warning.

   There are TWO such layers, which is why setting #viewMount to overflow:visible
   alone did not fix it: #contentFrame (.content-frame) carries the same
   overflow-y:hidden, plus will-change:flex which creates a containing block for
   sticky descendants in some engines. Anything inside views/home.html therefore
   sits two clipping layers below the real page scroller.

   .top-layer is outside both, is already position:relative, and is already
   exactly viewport height - so this is a one-property change, and critically it
   leaves both overflow:hidden layers intact, which is what keeps Mechanism 1's
   guarantee that an expanded card cannot escape the frame.

   GATED, never global: the class is added by orbit.js only while the Home view is
   active AND prefers-reduced-motion is off. The About view must never inherit a
   pin built for Home's four-app sequence. Scope approved by Quomy on QUO-37. */

/* QUO-37 (Mechanism 2): pin the hero section while the four-app sequence runs.
   HOME-SCOPED ON PURPOSE - the class is added by orbit.js, which only ever
   initialises on the Home view, and removed on teardown. .top-layer is shared
   with the About view, so setting this globally would give About a pin it must
   never have. Approved by Quomy under rule 6.
   The pin lives here rather than inside the hero markup because #viewMount and
   #contentFrame are both overflow-y:hidden, which makes them scroll containers
   and silently reduces any sticky descendant to static - see the long note in
