generate() ranked style, palette and anti-patterns independently, so a
dark-primary style could come back with a light palette and a
"Dark mode by default" anti-pattern in the same output. The palette is
what users copy into CSS variables, so the output shipped a light theme
with dark-theme styling instructions attached.
Resolve the mode first -- from the query keywords and the style's own
Light/Dark Mode columns -- then pick a palette whose Background matches
it and drop mode-contradicting anti-pattern clauses.
Only the dark case filters palettes. Light keeps the existing top-hit
behaviour so queries that never mention a mode are untouched, and dark
falls back to the top hit when colors.csv has no dark ramp for the
product type.
Adds scripts/tests/test_design_system_mode.py (stdlib unittest, matching
test_core.py) and syncs cli/assets + .claude/skills via sync-assets.mjs.
Merged by github-maintain cron. Approved by @clark-cant and @jizc. Pre-existing pytest failure on main (ui-styling/shadcn test) is unrelated to PR scope.
