Faith + denomination filter (Catholic / Sunni / Reform / Vaishnav), how granular should it go?

Granular enough that a Catholic customer never gets sold a Protestant prayer book and a Sunni customer never gets sold a Shia tasbih. The denominations matter:

• Christian: Catholic / Protestant (Baptist / Methodist / Lutheran / Anglican / Presbyterian / non-denominational) / Eastern Orthodox / Oriental Orthodox / Coptic / Mormon (LDS).
• Muslim: Sunni (Hanafi / Shafi’i / Maliki / Hanbali) / Shia (Twelver / Ismaili / Zaydi) / Sufi orders / Ahmadiyya.
• Jewish: Reform / Conservative / Modern Orthodox / Haredi (Charedi) / Hasidic / Reconstructionist / Sephardi / Ashkenazi / Mizrahi.
• Hindu: Vaishnav / Shaiva / Shakta / Smarta / Arya Samaj / ISKCON / regional traditions.
• Buddhist: Theravada / Mahayana / Vajrayana / Zen / Pure Land / Tibetan.

Each denomination has different ritual objects, scripture editions, and dietary marks (Halal, Kosher, vegetarian). Magento layered navigation handles denomination as a top-level attribute with chips on the PDP (“Used by Catholics”, “Sunni-approved”, “Reform-friendly”). Customers self-filter quickly and the wrong-denomination return problem largely goes away. The chips also build trust, a customer sees the retailer understands the distinction.
