# lit-agent — re-pin diff (NOT APPLIED)
#
# NOT BLOCKED. The 2026-09-22 "migrate to gradio 6 first" ordering was reversed
# on 2026-09-25 (docs/ADOPTION.md §5): lit-agent adopts NOW, on gradio 5.50.
#
# The hunks below are the older POST-migration form — do not apply them as-is.
# The adopt-now form is:
#   - requirements.txt: add ONLY the bcc-ui-theme line; leave `gradio>=5,<6`.
#   - ui.py: put `theme=theme(), css=CSS` on the existing gr.Blocks(title=...)
#     constructor (ui.py:639 when this was written — re-find it). NOT on
#     launch(): launch() on 5.50 has no **kwargs and raises TypeError.
# That Blocks() line keeps working unchanged after a later gradio 6 migration.
#
# Hand-pinned: no requirements.in.
