 - **Structure:** six 44px stacked radios reused from `.theme-preference-option`, plus a caption under the group. Raman is marked 默认. Each option has a one-line description; selected rows show the same `Check` as the theme panel.
 - **Values (2026-09-28):** `raman` (default) / `lahiri` / `kp` / `true_citra` / `true_pushya` / `fagan_bradley`, shown as Raman（默认）/ Lahiri / KP / True Citra / True Pushya / Fagan-Bradley.

The label is spelled True Citra, matching the engine's `ayanamsa_display` that the chart page parameter table shows. Copy lives in `frontend/src/lib/ayanamsa.ts`; `profiles_ayanamsa_check` lists the same six.
