I'm using the new Theming introduced in ExB 1.19 and customized the Abyss dark mode theme for my application's theme. The text on the OK button in the sign-in prompt is almost unreadable due to the calcite-color-text-inverse value for dark mode themed apps being nearly black (#141414):

Inspecting the button in DevTools, I see these are the variables that control the color the button elements use:
:host([kind="brand"]) button, :host([kind="brand"]) a {
--calcite-internal-button-text-color: var(--calcite-color-text-inverse);
--calcite-internal-button-background-color: var(--calcite-color-brand);
--calcite-internal-button-loader-color: var(--calcite-color-text-inverse);
}
I'd prefer if the text on this button used the variable --calcite-color-text-1 or #ffffff but I'm not sure how to go about overriding the text color this button uses since it is not a custom widget I control with a style sheet. Has anyone had experience overwriting these values before?
