v0.3.1

• Rewrite the README, skill file and source documentation so the library argues its design from the shape of the problem rather than from named consumer programs, which a reader who installs this crate on its own does not have and cannot check
• Stop the served session page reserving a position for any kind of session: every session is a card in one column in the order the listener reported, each with the same slice of the viewport, and the person folds or drops what they are not using
• Widen the served page's column on a large screen rather than splitting it into two panes, since a second column would require deciding which sessions belong in it
• Rename example and fixture identifiers, and the proxy's handoff cookie, to neutral names so nothing in the published crate reads as a registry of real consumers
