/*
    The EventStage design system.

    Bootstrap 5.3 stays underneath — the grid, the dropdown, the utility classes — but every
    surface a person actually looks at is redefined here. Colour, radius and shadow live in one
    place, the token block below: somebody changing a shade edits that block rather than forty
    files.

    Every font is a system font. The content security policy allows no third-party origin (§23),
    so a webfont would have to be downloaded and self-hosted for very little in return.
