The Tooltip

The overlay is drawn as a small floating box, usually near the top of the screen, and it refreshes every frame as you look around.

• It appears only when you are actually looking at something - it clears itself when your crosshair points at empty air or the sky.
• The layout is compact and icon-driven, mixing short text lines with small icons (tool icons, hearts, meters) so it reads at a glance.
• The contents change automatically depending on whether the target is a block, a machine, or a living entity.
• Nothing about it is intrusive: it does not pause the game, block your view of the world, or require a keypress to summon.
