Dealt with that exact thing on a food truck site last summer, button kept getting eaten by the nav on my phone. Just added position relative and a z-index to the button and it worked. Wild that one line can fix a site that feels totally broken.

Yikes, two years of that and nobody said a word until the PM did the math? Sounds like the real cost was all those questions your designer was too polite to ask on the call. Kill it and make it a quick 5 minute standup or just move updates to Slack, because a meeting everyone secretly dreads is just a billable hour bonfire.

That washed out and gray" look is the classic tell that you were printing straight 100K next to somebody else's rich black, and yeah, it shows up bad on a box. For big solid areas I go 60 cyan, 40 magenta, 40 yellow, 100 black, which is the old standard and still works fine on coated stock. The catch is that mix is meant for large covers and heavy ink areas, not 8 point body text, because four hits on tiny type turns into mud and registration problems. Rich black on a box is normal, but you have to watch total ink coverage with your printer, since some shops cap it around 300 and that mix sits right at 240. Also keep in mind rich black is for looks, not for text, so leave the small stuff pure K.
