# Slices: the part of spr's UI one consumer uses, generated as readable source.
#
# Usage:
#   ./ctrl/ui.sh list                     # what can be sliced, and what each piece pulls in
#   ./ctrl/ui.sh scan APP_DIR...          # what an app uses; its framework copy against spr
#   ./ctrl/ui.sh slice FILE [--only N] [--list] [--force]
#   ./ctrl/ui.sh check FILE [--only N]    # writes nothing; exit 1 if anything is stale
#   ./ctrl/ui.sh reference [--check|--spots|--scaffold]   # the ui-reference page of /docs, from common/ui/src
#   ./ctrl/ui.sh selftest
#
# FILE is a run file (see soleprint/common/slice/ui.example.toml). It lives beside
# the consumer it describes, never in spr, and is named relative to where you
# stand — resolved here before the cd below would change what it means.
#
# `delivery = "dependency"` is for own projects: spr's names stay and a .spr stamp
# says where the copy came from. `delivery = "vendored"` renames through a mapping
# profile, drops the headers, writes no stamp, scrubs every spr word, and will
# not run without an explicit `notice`.
#
# This is not ./ctrl/theme.sh: that bakes parts into single pages inside spr.
# This writes a slice into a consumer, and checks it for drift both ways.
