/* iOS Safari draws an inline `<video>` in a native compositing layer, and that
   layer can paint above web content that has not itself been promoted to a layer
   — z-index says nothing about it. A 3D transform gives an open dropdown its own
   composited layer so the ordering is settled in the compositor rather than only
   in paint order. It does not move the element: the dropdowns are positioned by
   `style.left`/`style.top` (horizontal_settings_controller.js#positionDropdown on
   /videos, `toggleSocialDropdown` in social_feed/index.html.erb on /social_feed),
   and a transform composes on top of that without changing it.

   Applied on `.open` only, so nothing is promoted while it is `display: none`.

   ⚠️ This half of the iPhone dropdown fix is REASONED, NOT OBSERVED — no iOS
   device here, and Playwright's WebKit will not launch on this host. The other
   half, and the one with a mechanism that can be pointed at in the CSS, is the

     zero 3D translate is 2D-representable, so Chromium resolves both forms to

/* Narrow viewports: the bar SCROLLS sideways, and SAYS SO.
   ------------------------------------------------------------------
   History. Trello 304 was "top bar not working": at a 414px viewport the button
   set is ~1026px wide on /videos and ~735px on /social_feed against a 358px
   container, so more than half of it — Min Likes, Date, Sort, Clear — is
   off-screen at any moment, and nothing on screen said so. The first fix
   (054c4fd) wrapped the bar. That reached every control but cost four rows on
   /videos and pushed the mobile header from 127px to 249px, roughly a quarter of
   the screen before the video starts. The owner asked for the scroll back.

   So: scroll restored, plus the affordance the wrap was standing in for.

   1. `flex-wrap: nowrap` — explicit, so it survives anyone re-adding a wrap rule.

   2. Edge fades on .horizontal-settings-bar::before/::after (below). Content
      visibly dissolves at the edge it continues past, which is what tells a user
      there is more without them having to discover it by swiping.

   3. `padding-inline` is deliberately the SAME width as those fades
      (--settings-bar-fade-w). At either end of the scroll range the first/last
      button therefore sits clear of its own fade, so a fade is only ever drawn
      over content that really does continue. That is what makes a static
      gradient behave like a direction-aware one, with no JS and no
      scroll-driven-animation support to depend on (which is the point — none of
      it can be tested against Safari on this host).

   4. `scroll-snap-type: x proximity` + `scroll-snap-align: start` on the items,
      so a swipe settles with whole buttons in view instead of a half-clipped one
      (a half-clipped button is what reads as "cut off" rather than "scrollable").

   5. The scroll region is inset from the two screen edges (`margin-inline`) and
      carries `overscroll-behavior-x: contain`. iOS Safari's back/forward swipe
      starts in roughly the outer ~16px of the screen; a horizontal scroller that
      reaches the edge competes with it. Inset, a touch that starts in that strip
      lands on the non-scrolling bar and Safari gets its gesture unambiguously,
      and `overscroll-behavior` stops a swipe that runs off the end of the bar
      from chaining outwards. ⚠️ This REDUCES the contention, it does not remove
      it — a horizontal drag that starts inside the bar is still a horizontal
      drag inside a `position: fixed` header. Not verified on a device.

   The 768px cut-off matches the rest of this file's mobile block. */
