build / build (push) Successful in 30s
shows the daily tarot/astrology reading on-device: persistence, reading computation, and UI screens, driven by the existing engine/interpreter code linked in unchanged where possible. Required engine-side changes to make that linking work: - A compact low-precision ephemeris (lowprec_ephemeris.c) replacing the vendored ~127KB Astronomy Engine, which doesn't fit the watch's ~64KB app budget. - Hand-rolled sqrt/atan2/sin/cos replacements for that ephemeris and astro.c's Ascendant calculation - Pebble's statically-linked libm hard-faults on real hardware under this app's -fPIE link for all four. - narrative.c/guidance.c refactored from FILE*/fprintf onto snprintf- based buffers, since Pebble's SDK blocks fprintf at compile time.
