// App-wide tooltip styling: a compact (small padding) and slightly-translucent tooltip. ImGui has
// no tooltip-specific padding (tooltips inherit WindowPadding, shared with every window) and PopupBg
// is shared with menus/combos, so we can't restyle tooltips via the global style without side
// effects. Instead, every tooltip goes through these wrappers, which scope the style to the tooltip:
//   dragonx::ui::material::Tooltip("fmt", ...);            // replaces ImGui::SetTooltip
//   if (material::BeginTooltip()) { ...; material::EndTooltip(); }  // replaces ImGui::Begin/EndTooltip
