Every crumb above the page you're on links to where it names: the section goes to its home (Parties › Stephen Waits → Parties), and a reconciliation's trail runs Accounts › its account › it. Same look; a pointer and "Go to …" on hover. A crumb naming the current page isn't a link.

//! The breadcrumb links back up: every crumb but the page you're on goes

//! GOAL: from Parties › Stephen Waits, clicking "Parties" goes back to the
|
||
//! directory; deeper trails link each level.
|
||
//! SOURCE: DECISION (Stephen, 2026-10-16: "I should be able to click
|
||
//! parties and it takes me back there ... when it goes deeper").
|
||
//! INVARIANTS: palette::crumbs 1-3, and
|
||
//! 4. Clicking a crumb goes to its route (a history step, so Back
|
||
//! returns).
