A chain: a head element followed by zero or more chain operations.
Each operation introduces a new element via the : operator. The
old .X detail-drill operator is gone — detail navigation is now
uniform with keyword filtering: :keyword mid-chain auto-extends
the candidate space with detail names at the current via depth.
The . token survives in the lexer for namespaced atoms inside
bracket bodies (prop.X, mixin.X), but it never appears as a
top-level chain operator.
