| description | Pull-only palette helper. Produce a visual design brief (_palette/design-brief.rst) and an optional design-preview.html for the current phase when the user wants that depth.

palette-ui — design brief (optional, pull-only)
This is an optional, pull-only palette helper. It is not part of the default loop (backlog → slice → stories → hand off → review), and must never run unprompted as part of slicing or story generation. Produce _palette/design-brief.rst (and, if useful, _palette/design-preview.html) only when the user asks, or when the current phase needs a visual language defined before stories can be written. Follow the RST house style (robust subset — no tables) in the always-loaded palette rule ({{PALETTE_RULE_FILE}}).
Prefix messages with [palette-ui]:.
When to use
The phase introduces or depends on visual elements, components, or styling the stories will reference, and the user wants the visual language set first.
What it produces
_palette/design-brief.rst — the visual language (palette, typography, components). Written once, extended (not rewritten) on later phases._palette/design-preview.html — optional browser preview mockup. This one stays HTML, not RST, because it is a rendered artifact the user opens in a browser.

Forbidden
- Not part of the default loop — do not run unprompted during slicing or story generation.
- Do not write or fix source code; this skill writes only
_palette/design-brief.rst and the optional _palette/design-preview.html.
- Do not use tables or nested RST directives in the brief — follow the robust subset. (The preview stays HTML.)
