Weekly Horoscope (public, no key)

Sun-sign weekly horoscope. The cache key anchors to the week's Monday, so any day in the week returns the same reading (and a finite number of generations per week). _footer watermark. The text comes in sections (overview, love, career, health, finance, advice; null in the rare answer that missed one) and as horoscope, the same sections as plain paragraphs, without headings or markup. Computed beside it, from the sky at noon UTC of date: transits (each planet with its sign and solar house counted from the requested sign, the sign itself being the 1st), aspects, events in the period (ingresses, stations, lunar phases, UTC), energy (a 1-10 score with every factor listed; a stated heuristic, not a classical technique), lucky (the sign's traditional ruler, its weekday and Cheiro number) and compatibleSigns (same element and the complementary one). When the text cannot be written right now (reason: "ai_unavailable") or is not ready within 15 s ("ai_slow", it is still being written for the next reader), the answer is 200 with X-AI-Cache: STALE and fallback: { reason, textDate, textLanguage }: the most recent text for this sign in the requested language from up to two periods back, otherwise the English one. The computed fields are always for date. 503 AI_UNAVAILABLE only when no such text exists.
