/* ── Rail ────────────────────────────────────────────────────────────────
   Deliberately chrome-less: no box, no heading, no footer — just the banners,
   like the aggregator strips this mirrors. Disclosure is the per-slot "Ad" tag.
   The track holds every slot rendered TWICE, so translateX(-50%) lands on a
   pixel-identical frame and the loop is seamless. shieldx-ads.js owns that
   duplication — if you change one, change the other. */
/* padding:0 is load-bearing — premium.css puts `padding-block: 116px` on every
   bare <section> at ≥1100px, and this rail is a <section>. Without the opt-out
   it inherits 116px top AND bottom on desktop. */

/* ── Short-viewport budget ───────────────────────────────────────────────────
   Measured on a 1560×660 laptop (the reported case): the rail is 112px of slot
   plus panel margin, and the token grid did not start until y=222 — 34% of the
   visible screen spent before a single token, on a rail whose slots are all
   unsold "Your ad here" placeholders. Paid space earns its height once it is
   paid for; empty space should not cost a third of the fold.

   Height-based, not width-based: the complaint is vertical crowding, so a
   short-but-wide laptop gets the relief while a tall monitor keeps the full rail.

   Placed at the END OF THE FILE deliberately. The first attempt put this block
   above `.adx-slot { height: 112px }` and barely moved the number (34% → 32%),
   because a media query adds no specificity — the later plain rule simply won.
   Same specificity means source order decides, so this has to come last. */
