# Bump mobile + hub to the same version. Updates pubspec.yaml's version:
# line (YYYY.MMDD.HHMM-alpha+N) and hub/internal/buildinfo/buildinfo.go's
# Version constant in one shot. Usage:
#   make bump VERSION=2026.722.219-alpha
# Versions are date-based CalVer YYYY.MMDD.HHMM (UTC build time). Mint
# the stamp from UTC, never the machine's locale time:
#   make bump VERSION=$(date -u +%Y.%-m%d.%-H%M)-alpha        # GNU date
#   (portable: date -u +%Y.%m%d.%H%M | awk -F. '{printf "%d.%d.%d", $1,$2+0,$3+0}')
# The build-number suffix (+N) is minutes-since-2020-01-01-UTC — a monotonic
# int32 Android versionCode that (unlike MAJOR*10000+MINOR*100+PATCH) does
# not regress at the day boundary where HHMM wraps 2359→0. CI recomputes
# the same value from the tag; keep the two formulas in sync.
