     TABLES → CARDS conversion on mobile.

     Every <td> in the JS-rendered tables now has a data-label="..."
     attribute. On mobile we hide the <thead> (column headers no
     longer make sense in a stacked layout) and turn each <tr> into
     a card by setting display:block. Each <td> shows its column
     label via a ::before pseudo-element on the left, and its value
     on the right.

     This applies to: plants.html main table, companies.html asset
     drilldown, capture-index.html full index, plant.html Top Days.
