1) Server + Bruno

Start server: cd server/NeonSprawl.Server && dotnet run.
curl -s http://localhost:5253/health returns JSON with status: ok.
Happy path (same order as folder seq): Post hotbar bind slot0 pulse → Post target select alpha before cast → Post cast happy — cast accepted: true.
Post cast happy alone (no target select in session) — expect accepted: false, reasonCode: invalid_target (or run curl with loadout + no lock).
After lock + loadout, curl cast with targetId: prototype_target_beta while lock is alpha — invalid_target.
After lock + loadout, move player far from alpha (POST …/move-stream with a distant position), then cast with alpha — out_of_range.

With server running, open main scene; hydrate hotbar (NEO-29); bind slot 0 to prototype_pulse if needed.
Without Tab lock, press 1: left HUD CastFeedbackLabel shows ability_cast_denied: invalid_target (or equivalent); Output may still show ability_cast_denied warning.
Tab to lock alpha; press 1: CastFeedbackLabel shows Cast: accepted; Output still prints ability_cast_requested when POST queued.
WASD until target HUD shows Validity: out_of_range (soft lock); press 1: CastFeedbackLabel shows ability_cast_denied: out_of_range.
