Coda — Reach for the primitive

No role by design — the keyword is already the vocabulary, or it's a named edge.

Type — weight & tracking (no role)

token	description
--font-weight-light	300 — nothing in the chrome uses it; offered for display type
--font-weight-normal	400
--font-weight-medium	500
--font-weight-semibold	600
--font-weight-bold	700
--letter-spacing-normal	no tracking
--letter-spacing-wide	the widest tracking the chrome uses
--letter-spacing-wider	wider than the chrome ever went — for small caps and labels
--line-height-flush	1 — single-line chrome
--line-height-tight	headings
--line-height-normal	running text
--line-height-loose	long-form reading, looser than the chrome needs

Space — named edges

token	description
--space-void	a deliberate 0
--space-hairline	1px, does not scale

Borders — edges & specials

token	description
--border-radius-void	sharp (0) — what Classic sets everything to
--border-radius-circle	circle / ellipse
--border-radius-pill	pill
--border-width-1	the standard hairline, behind --border-width-default
--border-width-2	a 2px edge
--border-width-4	a 4px edge — heavier than anything the chrome draws
