every non-base font size was a raw tailwind utility, so the design system's scale was documented in Typography.svelte and app.css but only actually used by Typography itself. the raw sizes now map onto the tokens: text-xs -> text-paragraph-small (12px, exact) text-base -> text-paragraph-large (16px, exact) text-xl -> text-heading-4 (20px, exact) text-2xl -> text-heading-3 (24px, exact) text-3xl -> text-heading-2 (30px, exact) font-mono text-xs -> text-monospace-small text-sm is left alone: it is 14px, which is the base body size, and the base size is out of scope. text-lg (18px) is not on the scale, so each one snapped by hierarchy: the subsection h2s in repo/new and the settings tabs go down to paragraph-large so they stay below their paragraph-large h1s, while the profile display name and the repo title go up to heading-4 so they stay above the body copy under them. the heading tokens also carry a weight, so anything that was rendering at 400 keeps an explicit font-normal — the marketing lede, the login tagline, the issue title and the repo title row. adopting the heading weights there is a design call, not a refactor, so it's left for later. verified computed sizes and weights are unchanged on the marketing home, login, repo and issues pages, and read the storybook renders for the primitives.
