The rail titles took the dock's rem type inside fixed 176px launchers, so a
larger browser font cut collapsed titles such as Recent Imagery short. Cap
the rail type at its 16px-root size.
The compact type for translated titles now skips Chinese and Japanese,
which fit at full size and keep their 9px floor, and reaches only the rail's
own launchers, so Radio inside Context keeps its type.
Tests now check the launcher divider, gap, toggle margin and flex-shrink
rules by their declarations, not only their selectors.
Collapsed Recent Imagery (English) and Data Layers (Portuguese) pushed
their toggles out of the card. Collapsed rail launchers now drop the
divider and pack closer, translated collapsed titles use compact type,
and any title that still does not fit ends in an ellipsis.
The hover now matches the dock trays' hover rather than their pinned
look, only on pointers that can hover, and recolours only the hovered
panel's own header, so Radio and body labels keep their colours.
The cyber theme keeps main's gutters and Display toggle size, the dock
and rails share --dock-label-* tokens, and the dimmed open Context title
rule is gone.
