/**
 * CAPABILITY: an N-way `.switch` — the many-armed sibling of `.branch`.
 *
 * A case matches when `<discriminant> === <case value>`, compared STRICTLY, so
 * the value's type counts (the ranks below are strings, so the cases are
 * strings). The optional last function is the DEFAULT arm, taken when nothing
 * matched. Each arm ends in its own `.return()`.
 *
 * Generic scenario (a dojo belt rank → what its next grading needs) so it reads
 * as "here is the switch shape", not as any task's expected output.
