//! Canonical design-token conventions (spec/TOKENS.md), shared with the
//! TypeScript DOM client: the Rust renderer consumes these tables directly, and
//! `pathland-ts-codegen` emits the TS equivalents from them — so the
//! `--pl-*` naming, the `dark.` scheme prefix, the generative `space.<N>`
//! family, and the length-token rules cannot drift between the renderers.

/// The scheme prefix stripped when naming a CSS variable (`dark.color.primary`
/// overrides the same `--pl-color-primary` inside a dark media query).
pub const DARK_PREFIX: &str = "dark.";

/// The CSS custom-property prefix for every token variable.
pub const VAR_PREFIX: &str = "--pl-";

/// The generative spacing family: `space.<N>` resolves to
/// `calc(var(--pl-space-base) * N)`.
pub const SPACE_FAMILY: &str = "space.";

/// Token paths whose F32 values are CSS lengths (emitted with `px`): the value
/// renders with a `px` suffix when it matches any of these leading prefixes.
pub const LENGTH_PREFIXES: &[&str] = &[
    "space.",

    "border.width.",

/// maps to `-`. (ASCII alphanumerics plus `-` and `_`.)
