   ------------------------------------------------------------
   Shared engine styling (js/help.js's TOC/search/print, rendered
   into three different hosts) plus the floating help icon + overlay
   used by guests and no-org signed-in visitors. All three hosts are
   dark surfaces already (Admin Board, client portal, marketing site),
   so one look works everywhere; only the accent color is retargeted
   per host below.

   FLOATING HELP ICON — guests + no-org signed-in visitors.
   Fixed left, cleared above the dockbar so it can never sit under the
   question bar; opposite the bottom-right .cookie card so neither can
   ever overlap the other.
   --dockbar-real-h is js/help.js's own live measurement of #dockbar's
   actual rendered height (a ResizeObserver, kept current across resize/
   orientation change/content changes) -- --dock-h alone is just the grid
   row's nominal single-row height and badly undershoots on phone, where
   css/08-responsive.css stacks three rows (dock-tabs, sector-pager,
   question bar) inside that same footer. --dock-h stays as the fallback
   for the brief window before JS has run its first measurement.
