// MARK: Style Demo (disposable demo/debug classes)
//
// These `.dbx-style-demo-template-<key>` classes back the `className` levers in
// `@dereekb/dbx-web/style-demo` (DbxStyleDemoStyleTemplate.className). They are
// DISPOSABLE demo/debug classes: they exist only to drive the styling showcase /
// live token-override preview harness and should be removed once the styling
// migration they support is complete. They are NOT a dbx-web core runtime primitive.
//
// Each template re-points CSS custom properties; values reference `--mat-sys-*`
// tokens (per the component-token convention) except where an intentional demo
// override value (e.g. an exaggerated corner radius) is the whole point of the lever.
//
// Authored like `_shapes.scss` as an opt-in mixin and emitted via an
// `@each` map loop (the `_curated-colors.scss` pattern). Include the mixin once at a
// global/root scope; the `var(--mat-sys-*)` references resolve per-theme at use-site,
// so a single emission works under both light and dark themes.

/// Builds the component-shape token override map for a single corner-radius value.
///
/// Re-points the same Material component shape tokens that `dbx-components-shapes()` pins to the
/// baseline `8px`, plus the dbx component corner tokens that track the system scale
/// (`--dbx-content-pit-rounded-border-radius`, `--dbx-prompt-box-border-radius`,
/// `--dbx-corners-border-radius`, `--dbx-navbar-item-border-radius`).
///
/// EXCEPT the intentional `--mat-sidenav-container-shape` (0) and `--mat-list-active-indicator-shape`
/// (2px global pin) entries — those keep their deliberate non-default shapes. For the same reason
/// `--dbx-list-item-border-radius` (the `.dbx-list` row radius; medium default) and
/// `--dbx-list-item-card-border-radius` (card-list rows) stay excluded here — they are owned by the list
/// component, re-rounded only by the `pill-controls` (`--dbx-list-item-border-radius` only) and the
/// dedicated `list-corner-*` levers (both list tokens).
///
/// `$value` may be a literal (e.g. `0`) or a token reference (e.g. `var(--mat-sys-corner-medium)`); the
/// emitting mixin interpolates either form via `#{$value}`. Private to this module (`-` prefix).
