    /* ACTION BLUE - ClientManager's OWN accent, not a blue chosen here.
       
       The palette had no blue at all (accent is near-black navy, accent-2 orange), so a button
       built from it read as dark and inert: "black is too boring ... BLUE for ACTION".
       
       These are lifted verbatim from ClientManager's app.css - --cm-accent and
       --cm-accent-border - because "like our SAVE and VIEW inside" and "even our OPEN inside is
       BLUE" means the same blue, not a similar one. A first attempt used #1763d6, picked by eye,
       which would have been a near-match that looks like a mistake beside the real thing.
       
       White on #1b6ec2 is about 4.9:1, which clears AA for this size and weight. */
