/* Playgate — a review docket, not a dashboard.
 *
 * Severity is ORDINAL, so it is one hue stepped by lightness (blocker darkest).
 * Verdict is STATUS, so it gets reserved hues that never appear as severities.
 * Both sets were checked with the palette validator against these exact
 * surfaces; the grey deliberately sits below the chroma floor, because for
 * "not applicable" reading recessive *is* the meaning.
 *
 * Colour never carries meaning alone: every mark is paired with its label.
 *
 * Layout: two columns. An earlier version put the gate rail in a third 92px
 * column, where its own heading and legend overflowed, and dumped all three
 * report sections into one 13,000px scroll. The rail is now a horizontal strip
 * inside the sticky report header, and the sections are panes.
