# =============================================================================
# Giga + Age of Wonder Compatibility Patch — Dyson Sphere  [single unified line]
# Design (per user): the ONLY Dyson Sphere path is
#       Giga Dyson Swarm  ->  AOW (star-class) Dyson Sphere
# AOW's own Dyson Sphere/Swarm build buttons and Giga's direct Dyson Sphere build
# are all disabled (see zzzz_compat_dyson_swarm.txt and
# zzzz_compat_giga_dyson_overrides.txt).
#
# AOW_MEGA_dyson_sphere_entry below is now an UPGRADE-ONLY transitional structure:
#   * upgrade_from = the completed Giga swarm stages (dyson_swarm_3 + dyson_swarm_3_basic
#     + the star-class ones) AND AOW's own swarm variants (AOW_MEGA_dyson_swarm_2_*
#     and AOW_MEGA_dyson_swarm_3_*) — so a finished swarm of ANY kind upgrades into it.
#     Having upgrade_from also removes it from the build menu (no standalone AOW build).
#   * its on_build_complete (fires on upgrade too) reads the ACTUAL star class and
#     redirects to AOW_MEGA_dyson_sphere_0_<class> (a zero-build-time passthrough).
#     sphere_0 then cascades: sphere_0 -> sphere_1 -> sphere_2 (see
#     zzzz_compat_dyson_variants.txt), so the player lands on sphere_2 ("Initial").
#     From there AOW's own sphere chain (2 -> 3 -> 4 -> 5 -> disco) takes over.
#   * the "no existing megastructure" placement check was removed because the
#     structure being upgraded (the swarm) is itself a megastructure.
#   * the single-star-system check is relaxed when is_upgrading = yes, since a Giga
#     swarm can be built in binary/trinary systems that the AOW sphere normally forbids.
# Giga's swarm->Giga-sphere link is severed in zzzz_compat_giga_dyson_overrides.txt.
