/**
 * The resource row: the one row grammar Extensions and Skills share.
 *
 * A row is a checkbox, a status glyph, the resource's name, and one verdict word.
 * A clean row carries no glyph and no word, so the column reads as one shape
 * instead of a checkmark that comes and goes, and the eye finds the rows that
 * need it.
 *
 * Pure: the theme, the width and the model row come in, one clipped line comes out.
