Paint awake as sunshine, not accent

Awake rows in the sleep & wake list borrowed --accent, which meant purple did
double duty: it was the colour of "awake" and also the colour of "this row is
the one still running", so the two readings overlapped on exactly the row where
both applied. A warm gold takes the first job. Asleep against awake now reads
as night against day, which is the distinction the list exists to draw, and it
agrees with the ☀️ the timer pill already shows.

Two variables rather than one. --wake is the bright gold, for the stripe and
the open row's tint. --wake-ink is that warmth pulled dark, for the small
uppercase label, and it is the value that flips with the theme: a yellow legible
on white is not legible on near-black, and vice versa. Measured on the four
backgrounds it lands on, it clears 4.5:1 in both themes, ordinary rows and the
tinted open one alike — better than the purple it replaces, which only ever made
the large-text bar.

The gold sits near --pee, but the two never share a panel: pee is a dot in the
history log and a bar in the counts chart, awake is a stripe in a list of
windows.

Scoped to the list, as asked. The big timer card and the day-bar pill still
paint awake with the accent.

A wake window is just the gap between two sleeps, so the two lists were always halves of the same sequence, and reading them together makes “only a 45-minute nap after two and a half hours up” obvious in a way two separate lists never did. Whatever is happening right now is the first row, as in the history and notes logs. Each row says which it is and carries a stripe in its colour; whichever one is still running keeps the highlight" },
