 - **Structure:** four 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:** `raman` (default) / `lahiri` / `kp` / `true_pushya`. Copy lives in `frontend/src/lib/ayanamsa.ts`.

+- **Hint:** “之后的咨询、报告、星盘库和每日星语会按新岁差算。生时校正目前仍固定按 Raman，之后的版本才会跟着这项设置走。”
 - **Placement:** after `ProfileFields` on the self-profile form only. Not on other-chart save, not on `page.tsx`.
 - **States:** default, hover, selected (`aria-checked` only), keyboard focus. Switching does not clear a confirmed birth minute.
