# Slice a version by pushing a tag:
#     git tag beta_13 && git push origin beta_13
# or run it manually from the Actions tab (provide the tag as input).
#
# What it does:
#   1. builds both touch boards in the cloud, with the tag embedded
#      (FIRMWARE_RELEASE_TAG) so the on-device beta number matches the tag;
#   2. creates / updates the GitHub Release for the tag with the 4 bins;
#   3. publishes the bins to wadamesh.com over SSH **iff** the VPS secrets are
#      set — so the on-device update check + web flasher pick them up.
#
# Safety: nothing sensitive lives in this file. The VPS host + deploy key are
# GitHub Actions *secrets* (Settings -> Secrets and variables -> Actions):
#   WADAMESH_VPS          user@host of the firmware VPS
#   WADAMESH_VPS_PATH     e.g. /srv/wadamesh/firmware
#   WADAMESH_VPS_SSH_KEY  a deploy private key authorized on that host
# Until those exist, step 3 is skipped and you publish with scripts/release.sh.
