You own the token layer and are its only writer. Your job is to make "maintain
the same styles" true and verifiable.

**Read first**: `.agents/context/design-system.md` — it documents three drifting
palettes and a broken `@font-face`. **Load skills**: `design-tokens`,
`visual-regression`.

## The two decisions you must surface, not silently make

1. **Three palettes → one.** `--ink` exists as `#172f42`, `#122534`, `#173044`;
   `--paper`, `--muted`, `--line`, `--gold` likewise. Most deltas are
   sub-perceptual and can be canonicalized. `--blue` (`#527f9f` vs `#215675`) is
   visibly different — screenshot both and get a human decision.
2. ~~**The fonts have never rendered.**~~ **Settled 2026-09-05 — do not
   reopen.** The malformed `@font-face` was escalated and the human chose the
   real fonts. Manrope and DM Mono are self-hosted in `public/fonts/`, wired
   through `public/fonts/fonts.css`, which `BaseLayout.astro` links and the
   legacy root `styles.css` `@import`s. **Do not delete these faces and do not
   replace the stacks with `Arial`/`ui-monospace`** — that instruction is
   obsolete. You may add `--font-sans` / `--font-mono` tokens pointing at them.

## You own

`src/styles/tokens.css`, `src/styles/base.css`, and
`.agents/scripts/check-tokens.mjs`.

Deliver: one value per token, a named type scale (`--step-*`) replacing 14
ad-hoc `clamp()` triples, five named breakpoints replacing sixteen, and an
enforcement script wired into `pnpm run verify`.

## Preserve the house style

Flat colour blocks, `1px` hairlines, near-zero radius, tight negative tracking
on display type, `Georgia, serif` emphasis spans, and the `gap:1px` over a
coloured parent trick used for grid separators. That last one is deliberate —
never convert it to `border`.

## Done when

Every token has exactly one value, `check-tokens.mjs` passes, and before/after
screenshots at 560/800/1100/1600 px **plus the eight removed breakpoint widths**
are attached to your task report with every visible difference explained.
