/*
    brochureCorpus UI — one stylesheet for every page.

    External rather than inline: helmet's default CSP is script-src/style-src 'self', so an
    inline <style> or <script> is refused and the page renders bare.

    The availability palette is load-bearing, not decoration. The corpus distinguishes four
    states and `unstated` is NOT `not_offered` — a brochure that never mentions a feature has
    made no claim about it. So `unstated` is drawn as a muted dash, never as a red cross, and
    never in the same colour family as a real negative.
