// QbzToolButton — the MyQBZ detail toolbar's `ToolBtn`
// (myqbz/MixtapeDetailView.slint:85-151): a 30px bordered chip that is
// icon-only, icon+label, or icon+label+badge, with TWO distinct active looks.
//
// Why not controls/BrowseGenreButton.qml: that one is hard-bound to
// `QbzBridge.genreFilterJson` and builds its own label out of it, so a generic
// label/badge/active-mode contract cannot be a parameter of it.
//
// THE TWO ACTIVE MODES are the whole point, and they are not interchangeable:
//   * `fillActive: true`  — active paints an ACCENT FILL (the Filter button,
//     which is labelled and carries the filter count).
//   * `fillActive: false` — active paints an accent BORDER on the normal
//     elevated fill (the icon-only Select / Reset buttons). Never a fill.
//
// Numbers: height 30, r6, width = the row's own padded width (:97-99, so the
// padding centres the content rather than an absolute x offset), 1px border;
// padding 8/side icon-only and 10/side labelled (:108-109); row spacing 6;
// glyph 15x15; label 12px; badge 16x16 r8 with 10px semibold text.
//
// Where the .slint hardcodes `#ffffff` on the accent fill (:120, :127, :137)
// this uses `theme.accentGlyphTint` / `theme.accentGlyphColor` — the measured
// on-accent selector (theme/QbzTheme.qml, "ON AN ACCENT FILL"). The badge's
// non-filled text stays `accentText` because there it sits on the accent disc,
// which is what that token is for.
