/* One scrollbar palette, site-wide (BO and Main Portal).
 *
 * Owner: “全站main/bo 的scrollbar颜色要统一”. Every scroll container in the product is the same
 * warm pill - light thumb #8B6B4A, hover #5C4A30; dark thumb #F59E0B, hover #D97706; transparent
 * track; no end arrows. That is the locked recipe (.interface-design/system.md -> Panel pill
 * scrollbar); what was NOT unified was the drift: slate #98A2B3/#667085, zinc #A1A1AA/#D4D4D8,
 * tan #EADCC8/#DCC9A8 and warm grey #57534E/#78716C on the same components in different families.
 * Those now state the house pair in their own sheets, so a scroller nobody has styled at all -
 * and the page-level bar, which was the raw OS default on EVERY page - get it here.
 *
 * Chromium: `::-webkit-scrollbar-*` only. Do NOT set `scrollbar-width`/`scrollbar-color` to a
 * coloured pair for it - Chromium then paints OS arrows and ignores every ::-webkit-scrollbar
 * rule (the trap recorded under Panel pill scrollbar). Firefox gets those two inside the
 * @supports branch below, where WebKit cannot see them.
 *
 * Specificity note: the two `*` rules are a FALLBACK, not an override. Any family rule - with or
 * without !important, all of which now state the same colours - out-specifies them, and a
 * deliberately hidden bar (`.report-sidebar .report-nav{scrollbar-width:none}`) still hides
 * because a standard property beats the pseudo-element.
