A bar-right toggle reveals a squarified treemap of the shown step's
context: category regions sized by tokens, with same-kind items folded
into one weighted block (every bash result together, skill loads by
skill, injections by form) and an 'others' tail past the fold cap.
Clicking a singleton block lands on its exact row (the DNA band pick's
path), a folded block filters the category's rows to the group's tag,
and a region header toggles the category like its row does. Block and
region hovers float a figure bubble and, outside DNA mode, report the
category to the shared composition hover; the open category keeps its
region framed.
