KP Ruling Planets

Computes KP Ruling Planets at a given moment (no natal birth chart). Request body: latitude, longitude, optional target_date, target_time, target_timezone. KP takes ruling planets at the moment of judgment, so with no target_date and no target_time the current instant is used. target_time alone means that time today; target_date alone means 12:00 on that date. Local date and time are read in target_timezone, which defaults to the time zone at the coordinates. target_utc and target_timezone in the response show the instant and zone used. A date not in the calendar (e.g. 2026-02-30) is rejected with 422 saying it does not exist; dates outside 1800-01-01 to 2099-12-31 are rejected with 422 too. A local time skipped by a daylight-saving change is read with the offset before the change (moved forward by the gap), a repeated time as its first occurrence; local_time_status says which applied. Works at every latitude, including inside the polar circles: only the ascendant is used, which needs no house cusps (the day lord still needs a sunrise). Returns day lord, Moon sign/nakshatra/sub lords, ascendant sign/nakshatra/sub lords, and the combined list of ruling planets in priority order.
