T1 scripts/birth_sky.py: real alt/az of the seven visible grahas (swe.calc_ut + swe.azalt, geometric altitude, azimuth converted from swe's south origin to north-east) and Yale BSC5 stars V<=4.0 (IAU 1976 precession); phase day / twilight_morning / twilight_evening / night. Thin POST /api/birth_sky registration in do_POST (no new handler method, no __new__). T2 GET /api/birth-sky?subject=: birth truth read server side through loadSubjectBirth + prepareChartViewProfile; zod contract; no billing, no writes, no birth data in the response. T3/T4 lib/birth-sky: sentence table, pure Canvas 2D drawBirthSky (night / paper palettes from DESIGN tokens, east on the left, serif headline with 1.5 s font wait), PNG export via navigator.share or Blob + a.download. Chart page prefetches and paints the cover once the chart is ok; the header button appears only when the PNG is ready. Dialog is a lazy chunk. T7 DESIGN §17, VOICE, CONTEXT glossary, CHANGELOG, real-device checklist.
