The bar showed each segment's share but not what it meant, leaning on the
coloured below/above-comfort text to explain it. Replace that text with a
per-card key directly under the bar: a colour swatch + plain name + share for
every bucket present (Too cold / Cool / Comfortable / Warm / Too hot), in the
same cold→hot order as the bar. Every span is spelled out, so a 1% sliver is
as clear as a 60% block, and small segments no longer need to fit a label
inside them. Bar segments also carry a hover title. The redundant top legend
is removed (each card now names its own colours), and the leftover summary
line keeps just the tolerance share and typical miss.
