   (tier-tip, notes-tip, image-tip below) switched from position:
   absolute to position: fixed, so a scrollable ancestor with
   overflow-x: auto (e.g. .table-wrap) can't clip them anymore — the
   same fix already proven for the header credit-tip popup, applied
   here too now that it was found affecting these as well. Unlike
   credit-tip's one predictable spot near the header, these can appear
   at any row's position in a table, so a single hardcoded fixed
   top/left won't work — the script positions each one against its own

/* ---------- Header "Credits" balance hover popup (§53, fixed §54) ----------
   position: fixed rather than absolute — .nav-links has overflow-x: auto
   (horizontal scroll for a long nav on narrow viewports), and per the CSS
   Overflow spec, setting overflow-x to anything but visible forces
   overflow-y to become non-visible too, even though it was never set
   explicitly. That was silently clipping this popup, since it's
   positioned to extend below the trigger — position: fixed escapes any
   ancestor's overflow clipping entirely (verified: :hover/:focus-within
   matching is unaffected either way, since pseudo-class matching is based
   on the DOM tree, not the rendered layout position). Positioned as a
   fixed offset from the top-right of the viewport rather than tracking
   the trigger's exact position, since the trigger itself sits inside a
   horizontally-scrollable container whose scroll offset can't be
   followed without JavaScript — a stable, predictable top-right spot
   near the header (where Credits/Cart/Log out already visually cluster)
   is more robust than attempting pixel-perfect anchoring that would
   drift as soon as anyone scrolled the nav. */
