Boundary blend zone (sign-cusp / house-cusp transitional zone)
A term from astrology, defined plainly — and shown in context in your chart.
Definition
The range roughly ±1.5° around any sign or house cusp where both adjacent signs' energies are simultaneously active. Replaces the traditional "anaretic degree" framing. A planet at 29° of one sign carries its sign's content fully and also senses the next sign's incoming pull.
