feat: Astro landing for @bearstudio/ui-state

[HugoPerard]

Summary

Marketing landing for @bearstudio/ui-state as an Astro 6 SSG app at apps/landing, against this TS 7 / oxlint / oxfmt branch. Unpublished; no changeset. Does not touch draft PR #1.

English at /. One primary CTA: GitHub + pnpm add @bearstudio/ui-state. Hero is zero-JS product UI (README match + exhaustive sample + pending/error/default cards). One React island (StateDemo, client:visible) uses workspace:* and demos pending / error / default with match + exhaustive and when. Public API not widened.

How to run

From repo root (Node 24, pnpm 10.34.5):

pnpm install
pnpm --filter landing dev

Root pnpm dev / pnpm build / pnpm check-types / pnpm lint include the app via turbo. Landing dev has dependsOn: ["^build"] so packages/ui-state dist exists before the island imports it.

App: check-types = tsc --noEmit on the island. Lint = oxlint. Format = oxfmt. astro check is not the source of truth (TypeScript 7 has no compiler API).

Stack

• Astro 6.4.8 SSG + @astrojs/react 6.0.4 island
• Tailwind 4.3.3 via @tailwindcss/vite (not @astrojs/tailwind); tokens in @theme inline
• Fonts: Astro 6 Fonts API, Fontsource, IBM Plex Sans/Mono, latin + latin-ext, self-hosted (no fonts.googleapis.com). Sans preloaded; mono not
• No GA4, CMP, cookie banner, fake stats/testimonials

tsconfig split

• Library unchanged: NodeNext via react-library.json
• Landing does not extend react-library.json. It extends new packages/typescript-config/astro.json (module: ESNext, moduleResolution: Bundler, noEmit)

Files

Workspace / toolchain:

• pnpm-workspace.yaml (apps/*)
• .gitignore (.astro)
• .oxlintrc.json (**/.astro/**)
• turbo.json (dev.dependsOn: ["^build"])
• packages/typescript-config/astro.json

• apps/landing/package.json

Lockfile / what failed remotely

pnpm-lock.yaml is still the PR #4 lockfile (importers: root + packages/* only). Could not run pnpm install or tsc here (no git clone; package-manager invocations were blocked). After checkout: pnpm install from root, then pnpm --filter landing check-types / build. CI on this PR is the first real install + build.

Canonical/OG URL is the GitHub repo (no production host yet). Static samples escape {/} with Astro expressions or HTML entities.

Test plan

• pnpm install (updates lockfile with landing deps)
• pnpm --filter landing check-types (tsc --noEmit)
• pnpm --filter landing lint (oxlint)
• pnpm --filter landing build
• pnpm --filter landing dev — hero has no JS; island hydrates on view; pending/error/default all render via exhaustive()
• Disable JS: page copy, code samples, GitHub CTA still work
