Typography round 4 (owner): the snap to the ladder — prose 16.5→16, xxs rung merged into xs
The system: the ladder is the truth, everything snaps to it. - Prose snaps to the ladder's 16px rung (--lh-prose-size 16.5→16; the half-pixel was a reskin-era hand-tune with no visible payoff and a system cost). lh-prose, lh-input, and the session titles all read the one variable — one reading size, now a ladder citizen. @theme inline inlines literals without emitting runtime vars, so the variable can't var()-link to --text-lg: documented as the one deliberate duplication (change one, change both). - The 10px rung merges into 11px: one pixel apart was a distinction with no visible difference, and 10px sits at the mono legibility floor — quiet labels (Sessions, Background agents, dock hints, model-picker footers) get their quiet from color + tracking, not a notch of size. All 13 text-xxs uses → text-xs; --text-xxs token removed. - Derived constant follows: TEXT_CAP_SCALE 16.5/12.5 → 16/12.5 (1.32 → 1.28; test pin 232.32px → 225.28px) — the plan-graph text cap now tracks the snapped prose size. Live: title 16px, Sessions/Background-agents labels 11px, composer 16px with the 20px lh-input line box. Gates: typecheck, lint, 469/469. Lane note: components/graph-context-marker.tsx (graph-stream file) had a mechanical text-xxs → text-xs swap — required: the token removal otherwise leaves a dead class in their file.
