 * The row box-model relationship between a row's logical height and the pixel height written to the
 * DOM. Pure functions of the border-box flag (`stylesHandler.areCellsBorderBox()`), so they carry no
 * DOM or engine dependency and are unit-testable directly.
 *
 * The size caches store the LOGICAL row height (the value the calculators and `sumCellSizes` sum). The
 * renderer writes a slightly different PIXEL height to each row element: in content-box mode it writes
 * `logical - 1`, because that 1px is "replaced" by the row's 1px top border, so the row still occupies
 * `logical` px in the layout; in border-box mode the border is included and it writes `logical`. Either
 * way the rendered row occupies `logical` px, which is why the logical cache total already equals the
 * DOM-occupied total.
 *
 * Centralizing the 1px constant here keeps that equality true when the border model is edited later. It
 * also lets the hider math size the hider from the cache total and agree with the sum of the pixel
 * heights the renderer actually wrote.
