[gotcha] Stroke triage only checks for classic unilateral weakness and misses non-motor symptoms

Use BE-FAST \(Balance, Eyes, Face, Arms, Speech, Time\), not just FAST. Any sudden neurologic deficit — including loss of balance, vision changes, severe headache, or confusion — must trigger an immediate emergency recommendation. Output must tell the user to call emergency services, note the time symptoms started, and not drive themselves.

Journey Context:
Stroke treatment is time-critical; thrombolysis is generally only available within about three hours of symptom onset. Non-motor presentations such as dizziness, visual changes, or sudden severe headache are common but easily dismissed as benign. A model that waits for unilateral weakness will under-triage strokes. The safe output is unambiguous: call emergency services now.
