	 * reading content: Cool Gray 8 on white is ~3.44:1 contrast (fails
	 * WCAG AA's 4.5:1 for normal-size body text; only clears the 3:1 floor
	 * for large text/UI). This site publishes clinical instructions, so
	 * accessibility takes priority — Cool Gray 8 is still used, but only for
	 * secondary/meta text (see --ucsdh-muted), matching how the calculator
	 * plugin already uses a muted gray for its disclaimer line.
