/* --rail-col / --rail-gap are the rail's column metrics, declared once here and stepped down in
   the media queries below. Every tile width derives from them, so a book cover and a resume tile
   cannot drift apart the way two hand-maintained ladders eventually would. (They never actually
   diverged -- the duplication was a standing risk, not a realized bug.) Discover.razor used to
   carry a second, contradictory ladder of its own (160/180/200/220/240/260) for the arrow scroll
   math; it now measures the rendered track instead, so this file is the only width ladder left.

   The var() fallbacks are the BASE values only: an item rendered outside a .streaming-carousel-track
   would size at 240px/12px at every viewport rather than following the ladder. Nothing renders that
   way today, and the fallbacks exist to avoid an invalid declaration, not to preserve responsive
   behaviour outside a track. */

/* A resume tile (16:9) interleaved into the continue-reading rail (cross-format Entries mode).
   It spans TWO columns plus the gutter between them -- the flex equivalent of the Library's
   `grid-column: span 2` (library.css), so the two surfaces agree. The reason is height, not
   prominence: a 16:9 thumb plus its fixed ~40px meta block at one column's width renders roughly
   half a 5:8 cover's height (measured 49% at a 240px column), leaving more empty column under the
   tile than tile. At two columns it measures 85-91% of a cover -- closest to parity at the narrow
   breakpoints, loosest at the 240px column. Under 576px the cap below trades some of that back for
   a visible next cover, bottoming out near 79% at 360px. The Library's span-2 tile sits in the same
   band.

   This SUPERSEDES the `align-self: center` introduced by #1751, which treated the same complaint
   (the dead gap under a half-height tile) by splitting the gap above and below instead of by
   removing it. With the tile at 85-91% parity there is only ~35-55px of slack left, and centering
   that would push the tile's top edge below the covers' -- the shelf's visual baseline is the top
   of the row, so a centred near-parity tile reads as misaligned rather than as deliberate. Width
   fixes the cause; alignment only redistributed the symptom. Hence flex-start.

   These selectors outrank watch-show.css's own .wsp-continue-card width, so they win wherever the
   tile renders in a carousel without needing !important.

   NOTE on scroll-snap, corrected after measurement: a snap container does NOT simply snap to the
   nearest tile edge. After a layout change it re-snaps to the element it was ALREADY snapped to,
   which is why inserting this tile at index 0 used to scroll it off screen. Discover corrects that
   explicitly via resetCarouselScroll (shared.js); the width here does not depend on it. */

       hero rather than a shelf and hides the fact that it scrolls. vw is used nowhere else in this
       file; it is safe here because the rule is scoped below 576px, where overlay scrollbars are
       the norm and the classic vw-vs-scrollbar discrepancy does not apply. */
