Lift the faint greys to something readable in a dim room

This is a dark interface used in poker rooms and kitchens with the lights down,
and I'd been generous with grey-on-black. Measured every piece of text against
what's actually painted behind it: thirteen declarations came in under 4.5:1.

The worst was the empty card slot's "+" at 2.63:1 — an affordance telling the
dealer the slot is tappable, and the least legible thing on the screen. Then a
run of #777 labels around 3.9 to 4.1: the standings header, the time on a logged
hand, the currency mark in the add-chips field. The rulings source line sat at
3.62 and the rulings link itself at 4.39.

All of them move up just far enough to clear 4.5 rather than being flattened to
white, so the hierarchy between a heading, a value and a hint survives.

Worth recording what the measurement can't see: it reads background-color, so
text on a gradient — the pot badge, the dealer button, the blind badges — comes
back as a false result in both directions, and those were checked by eye
instead. The felt watermark is deliberately at 6% and stays that way.
