For UI prototypes in the mvskills frontend profile, load design-system and use its theme, semantic tokens and typography from the start. Prototype fidelity does not relax the selected visual conventions.

For new-screen/flow exploration or substantial UI redesigns, load ui-ux-research through the host mechanism or read its installed entrypoint before drafting variants; reuse existing research.
