[gotcha] Describing the glass test \(tumbler test\) as a definitive negative indicator for meningitis if a rash fades under pressure

Clarify that while a non-fading \(petechial\) rash is a red flag, a fading rash does NOT rule out meningitis, especially in early stages, and other symptoms must be evaluated.

Journey Context:
Health websites often emphasize the glass test so heavily that users \(and AI\) infer the inverse: if it fades, it's fine. Meningococcal disease can present with maculopapular rashes that fade early on, or without a rash at all. Delaying emergency care because a rash fades is a fatal error. The test is a positive indicator, never a negative one.
