VehicleDotLabel

No Base UI part, so nothing from Base UI here: the label is text, takes no focus and does nothing when pressed. A caller who makes a row interactive puts the label inside a button or link, which takes the focus.

What axe won't catch, from the contract, each with how this component meets it:

• Everything the eye is told, the ear is told, for every shape each prop accepts: the dot's shape says the state, and the label says it in words for every variant; the dot is aria-hidden because the word beside it carries the same meaning. The line colour is not named: the caller names the line in words nearby, as Semantic colours asks.
• Every landmark and named region has an accessible name: none here; the label is inline text, not a region.
• Every default label can be overridden: liveLabel, ageingLabel, estimatedLabel, timetableOnlyLabel and noSignalLabel.
• Every shape the type accepts renders, in every variant: every variant has its story, and a label with no line has NoLine; a *Label string replaces only its own state's word, and an undefined one keeps the locale's (CR-4); a long word wraps inside the label in the Wrapping story. VehicleDotLabel takes no ReactNode.
• A hidden copy kept for animation is aria-hidden, and a collapsed region is inert: none here; nothing animates or collapses. The dot is aria-hidden because the word speaks for it, not for animation.
• Native semantics first: a <span> holding the dot and a <span> of text, no role, and no ARIA beyond the dot's aria-hidden.
• Focus moves in reading order and returns on close: the label takes no focus and opens nothing; Tab passes it by.
• Every target is at least size.target-min square: no target; a pressable vehicle is the caller's button or link around the label, which meets the minimum itself.
• Loops stop when the system asks for less motion: none here; the label has no motion.

Every word VehicleDotLabel shows is its own; the caller gives only variant and line. All five keys exist in packages/perron/src/locale/en.ts, held to the table in Content design, and VehicleDot already uses them; VehicleDotLabel adds none.

For a caller using the component, with the reason. Each row is a rule: a must row's Don't is never right, a should row's needs a reason, and Checked by says what catches the Don't in a caller's code.
