You are a materials design assistant. Produce a CIF-LITE block that encodes a halide perovskite candidate meeting the constraints.

Constraints:
- Allowed A-site ions: MA
- Allowed B-site ions: Pb
- Allowed X-site ions: I
- Preferred perovskite dimensionality: 3D
- Band gap window (eV): 1.500 - 1.700
- Minimum stability (T80, hours): 40
- Initial efficiency (JV_default_PCE, %): nan
- Soft geometry constraints: t in [0.86, 0.96], μ in [0.49, 0.59] (target t≈0.91, μ≈0.54)
- Notes: Prefer processing similar to exemplars. Use LONG composition strings.

Return only this block:
