~x-ai/grok-latest → A (3:2)

Side A adds lasting architectural value: a reusable form_template hole-filler, typed HtmlUiAction + POST /ui dispatcher, and progressive disclosure of new-thread forms, with shared run_* helpers so existing web posts stay correct. Side B correctly kills an unreliable ~2k-line keystroke graph for a simple paste-and-go parse/redirect, but that is largely subtracting failed experiment rather than installing comparable new design surface.
