//! Framework default theme tokens.
//!
//! [`install_default_tokens`] installs the colour and font tokens every
//! Hydrolysis runtime needs before a [`Style`](crate::Style) applies its own
//! tokens on top. It is installed by both runtimes — the rendered runtime
//! before `style.install_tokens(&mut env)`, and the semantic runtime as its
//! only token source — so widgets resolve the same framework defaults whether
//! or not a style package is present.
//!
//! These tokens are *not* a theme: they carry no widget theme and no
//! presentation decisions beyond the framework's baseline palette and type
//! scale. A `Style` may overwrite any of them.
