                            4.79:1, passes AA for normal text. At UI scale cool
                            white on orange is 3.38:1 and marigold is 1.83:1;
                            both fail, so neither is available in this stylesheet.
                            DISPLAY-SCALE type is a different threshold — the
                            brand system's thumbnail template T4 puts a cool-white
                            numeral on orange at 3.38:1, which passes the 3:1
                            large-text rule. T4 is correct; do not "fix" it to
