/* <LinksMenu> — a single header icon-button + popover. Kept visually
   quiet (no border/fill until interacted with) so it reads as chrome,
   not another nav item. Button is sized to the same touch-target floor
   as the shared `ui/` kit (2.75em ≈ 44px, WCAG 2.5.5) even though it
   isn't built from that kit — a bespoke icon trigger, not a form
   control, but the floor applies regardless of which component drew
   it. No `margin-left: auto` here — `Shell.tsx`'s `.shell-header-actions`
   wrapper owns pushing the whole action group to the right edge now
   that `SettingsMenu` sits alongside this one. */
