 * THE TIME GRID — a day column per day over an hour rail, with the all-day
 * banners in a band of their own above it.
 *
 * The hour height and the gutter's width are the LAYOUT's numbers (the module
 * places every block against them), so they arrive as data rather than being
 * declared twice: `--lotics-time-grid-view-hour` and `-gutter`.
