The navigation was a bar across the top that did not fit on one row — six page entries and the session block against the panel's width — and had to be split into two, costing the top of every page. It is now a column down the left edge: one left edge to scan, the current entry marked down its leading edge, sticky so it stays in view, and room under the entries for the current page's own sections. Below the width the two columns need it lies back down into the same wrapping rows as before; six entries need no drawer. The section index is for the two pages long enough to need one — the domain page (nine cards) and the status page (eight). Each card carries an id and the page's template defines the list by overriding an empty "sections" block in the layout, so a page that defines nothing renders no index. panel.js marks the section in view, looking targets up by id on each pass so the status page swapping its cards out every five seconds cannot leave it measuring boxes that have left the document; the links themselves are plain fragment links and need no script. Verified against the real pages rendered by a local panel at 1300px, 924px and 481px wide.
