                                    It happens to clear 4.5:1 on the page
                                    backgrounds, but the rule is still: never
                                    let it carry body text or a control border.
     --color-accent-text  #7C4059   Every letter and every control/state border.
                                    7.26:1 on --color-bg, 6.62:1 on --color-bg-alt,
                                    7.68:1 on white.
     --color-border-strong #8E828A  Form fields and floating buttons.
                                    3.48:1 / 3.17:1 / 3.68:1 — clears the 3:1
                                    non-text requirement on all three grounds.
