/* Sticky header variant (tracking/zip_list.html, portfolio_list.html,
   tracking/proxy_list.html): the page itself scrolls (no bounded inner
   scrollport) — the header row just sticks to the viewport, docked
   against `.site-header` with the "pushed down a bit" look coming from
   `padding-top` instead of an actual positioning offset — a real gap
   between the two sticky boxes is a seam neither of them paints, so
   whatever body row is mid-scroll at that exact band shows through it
   (see the `top` comment below for why it's a deliberate 1px *overlap*,
   not an exact `top: var(--header-height)` flush join). `.site-header`'s
   `z-index: 10` staying above this header's `z-index: 1` is what makes
   that overlap invisible.

   Two overflow overrides are required for `position: sticky` to actually
   track the viewport instead of silently no-opping (confirmed by hand:
   without these, the `th` renders at "natural position + top", i.e. it
   never detaches, it just sits permanently offset and scrolls away with
   the page):
   - `.table-scroll--sticky` itself: cancels the bare `.table-scroll`'s
     `overflow-x: auto`, which per the CSS overflow-computation rule
     silently forces `overflow-y` to `auto` too (you can't have one axis
     `visible` and the other not) — that makes this div its own "scroll
     container" with an empty scrollport `position: sticky` sticks to
     instead of the real viewport.
   - `.table-scroll--sticky table`: the plain `table` rule below sets
     `overflow: hidden` (to clip cell backgrounds to its rounded corners),
     which is exactly the same kind of non-scrolling "scroll container"
     ancestor and just as fatal to sticky here — this override wins on
     specificity (one class + one element beats one element) regardless
     of the two rules' source order. */
