The Insights screen's whole job is showing what the app has learned, and
its cycle history was a column of numbers -- the least legible form of the
one pattern a user actually wants to see.
A bar per cycle now, Compose-drawn with no chart library, scaled to the
longest with a floor so a single cycle does not fill the card and read as
"long". A cycle outside her usual range is filled differently AND says so
in its label, and the range itself is stated in words underneath.
The number never leaves. A bar chart is exactly where §43's rule -- that
nothing is legible only as a shape or only as a colour -- gets forgotten,
because the picture reads so well to whoever built it that the number
feels redundant. The bars annotate the numbers; they do not replace them.
A screen reader hears one sentence per cycle, and it is the same sentence
a sighted user reads beside the bar.
With no usual range established, nothing is called unusual: one cycle is
not a pattern, and this card must not imply it is.
Proved: dropping the "outside your usual range" half of the label reddens
exactly one test.
