FactList

FactList has no keys of its own and is never focusable. A value the caller makes a link or button brings that element's own keys, in reading order.

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: each name and value is read as shown, name first; "—" is aria-hidden and the ear hears "Unknown" in its place (CR-5). No colour carries meaning: values are color.text.primary, and tertiary only for the "—" the words speak for.
• Every landmark and named region has an accessible name: none here; the dl is a list, not a landmark or region, and a caller who names it gives aria-label or aria-labelledby on the root.
• Every default label can be overridden: unknownLabel.
• Every shape the type accepts renders, in every variant: label and value are ReactNodes; a string, a number, an element and a list each render, 0 is a value and not unknown (CR-4), an empty items renders an empty dl (CR-8), and FactList.test.tsx renders each shape. The Default story gives string names and values.
• A hidden copy kept for animation is aria-hidden, and a collapsed region is inert: none here; nothing animates or collapses. The "—" is aria-hidden because the words speak for it, not for animation.
• Native semantics first: dl, div, dt and dd, HTML's description list, with no role and no ARIA beyond aria-hidden on the "—".
• Focus moves in reading order and returns on close: FactList takes no focus and opens nothing; focusable values, such as links, come in the order of items.
• Every target is at least size.target-min square: no target of its own; a link a caller puts in a value is the caller's to size.
• Loops stop when the system asks for less motion: none here; FactList has no motion.

Every word FactList shows comes from the caller, through each item's label and value, but for the one it announces for a fact with no value.

A fact with no value shows "—" and says "Unknown", reusing Stat's unknown key. Content design writes "—" for unknown and the brand never shows a guess, while a screen reader skips or spells a bare "—", so the ear would hear a name with nothing after it; Stat and Delay do the same, and one word across the Display family keeps every screen agreeing. unknown, "Unknown", is the key Stat added to packages/perron/src/locale/en.ts, with Danish "Ukendt", Swedish "Okänd" and Norwegian Bokmål "Ukjent"; its JSDoc, which names Stat alone, widens to name any figure or value no data gives.

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.
