name: Mirror AMFI NAV + rebuild wheel

# Browser builds of tax-harvest cannot cross-origin fetch AMFI's NAVAll.txt.
# Mirror it to web/data/ on a daily cron so the static site reads a same-origin
# copy. Also re-build the tax_harvest wheel whenever the Python source changes
# so the web UI installs the latest engine.

    - cron: "0 18 * * 1-5"   # 18:00 UTC = 23:30 IST weekdays, after AMFI NAV publishes
