Hovering a history bar now transiently previews that step in the Context browser — picker, meta line, composition bar and category lists all follow the pointer, with a 'preview' marker in the meta row. Leaving the chart returns the browser to its own picker selection; a seq trimmed out of retention is ignored. Accordion state survives the hover, so one open category can be scrubbed across steps for comparison.
