regenerate-artifact

Recovers a failing artifact via three progressively conservative retry steps.

paperboard regenerate <slug>

validate-artifact returns FAIL and the artifact-reviewer recommends REGENERATE_VIA regenerate-artifact.
Never invoke without a prior validation failure — check first.

Step	Change	Rationale
1	Switch tier (cycle among atv / pico / daisy; atv is default)	Different tier/CSS framework may avoid inline color conflicts
2	Drop optional components from input	Reduces surface area for color violations
3	Fall back to `paperboard.DESIGN.md`	Known-good default design always lints clean

Prints: Regenerate step=<N> new_slug=<slug> status=ACCEPT|FAIL(<fail_class>)

Exit 0 on ACCEPT, exit 1 if all three steps fail.
