   resizes or repositions the dropdown, ZAR button, feedback area, or
   rename rows below.

   POPOVER — anchored, outside normal flow

   PATCH 2026-08-26 | UNSCOPED ON PURPOSE

   emc_mapping_hints.js moves this element to document.body at bind
   time (the MARSS dock wrapper sets transform/will-change:transform
   for its slide animation, which would otherwise make it the
   containing block for position:fixed here — the same clipping bug
   already fixed for the tooltip overlay). Once moved, this subtree is
   no longer inside .marss-emc, so these rules are intentionally
   unscoped and use literal colors instead of the --emc-* custom
   properties (which are also only defined inside .marss-emc's own
   scope) — mirroring emc_tooltips.js's .emc-tooltip-overlay exactly.
   The trigger BUTTON above stays in place and keeps using .marss-emc
   + var(--emc-*) normally.

   Lives in the third "Number of groups to rename" toolbar column

   the SAME column that already held only #emcAliasFeedback — this is
   deliberately scoped/normal (unlike the popover above, which is
   moved to document.body and therefore unscoped with literal colors):
   it never leaves .marss-emc, so var(--emc-*) tokens are available.

   Sized to feel like an input utility attached to "ZAR AI · Suggest",
   not a second large card: capped to a compact, roughly square
   footprint (never stretching to the column's full available width),
   while #emcAliasFeedback below it keeps that column's full width for
   wrapping its own (sometimes long) messages.
