The lobby connect menu and three pieces of the HUD (hit-flash overlay, boss bar centering, death-message centering, hint label) were all silently broken by the same Godot gotcha: set_anchors_preset(preset) with the default keep_offsets=false does NOT zero the offsets to the preset's margins -- it recomputes them to preserve the control's *current* rect, which for a freshly constructed Control is (0,0). Anchors end up correct; the actual rect stays pinned to the top-left corner regardless. Fixed by switching to set_anchors_and_offsets_preset() everywhere a Control is built in code, and by using offset_left/offset_top (anchor-relative) instead of .position (absolute) for the HUD hint label. Documented as gotcha #5 in CLAUDE.md. Also split PLAYER_RADIUS into two constants: PLAYER_RADIUS (6.0, the authoritative hitbox used by SimWorld) and PLAYER_VISUAL_RADIUS (13.0, view-only, used by world_view.gd). The client renders every ship a little late relative to the server -- interpolation delay, reconciliation smoothing -- so a hitbox that matched the sprite would let bullets connect against a ship the player watched dodge clear of them. A smaller hitbox means the occasional bullet visibly clips the sprite without a hit, which reads as more forgiving of latency than the reverse. Verified headlessly: a throwaway scene instantiating MainMenu/HUD under a real 1280x720 viewport, asserting the panel is centered and _canvas.size / hint position resolve correctly, before and after each fix. check.sh, test.sh (78/78) and smoke.sh all pass.
