Highlight key tokens in Make route params static fix card
Extends the snippet schema with an optional `parts` array so a single
snippet line can contain inline-highlighted segments. The renderer maps
each part to a `<span data-snippet-highlight>` child; the existing
line-level `highlight` flag still works when `parts` is absent. The
highlight CSS selector is broadened from `[data-snippet-line]
[data-snippet-highlight]` (compound) to a descendant selector so both
shapes pick up the per-card color.
Applied to the `Make route params static` card so only `generateStaticParams()`
and the entire `[{ slug: "…" }]` return-array literal are emphasized,
keeping `export async function`, the leading whitespace, and the
trailing braces in the default body color.
