Package keybindings embeds and exposes the canonical keybinding reference
data for grut. The JSON file in this package is the single source of truth
consumed by the help overlay and used to generate docs/keybindings.md.
Sections returns the ordered list of keybinding sections parsed from the
embedded JSON. The returned slice is a shallow copy; callers may replace
elements but must not mutate individual Binding slice contents in place.
