/*
* Layout helpers (see layout.css).
*
* Sticky headers: measures the top nav and each table's group header so the column
* header rows can stick directly beneath them (--nav-h, --sticky-top, --thead-r1).
*
* Card view: on phones and tablets each table row is shown as a card, with every cell
* rendered as "Column name: value". CSS can't look up a cell's column header, so this
* copies each header's text onto its cells as data-label.
*
* The dashboard re-renders its tables constantly, so both are reapplied (once per frame
* at most) whenever the DOM changes.
