m/paliad#52 (t-paliad-221) — the Compact/Comfortable segmented control
on /approvals was rendering its active pill in plain --color-surface
(white in light mode, midnight-tinted in dark). Switch to the brand
lime so the segmented controls speak the same primary-action language
as the rest of Paliad.
Introduces three semantic tokens (--color-segment-active-bg / fg /
border) so any future surface that adopts .filter-bar-segment
inherits the same accent treatment without a CSS rewrite. The tokens
resolve to --color-accent / --color-accent-dark in both themes,
keeping the midnight foreground WCAG-AA on lime.
