migrate web to next 16 template and redesign landing page (#526)
* migrate web to next-template stack (next 16, react 19, tailwind 4)

replace all infrastructure with next-template conventions:
- next.js 14 -> 16 (turbopack default, typed routes, react compiler)
- react 18 -> 19
- tailwind css 3 -> 4 (css-first config, oklch theme system)
- eslint 8 (.eslintrc) -> 9 (flat config with stricter rules)
- add shadcn/ui, base-ui, cva component primitives
- upgrade theme toggle to light/dark/system dropdown
- migrate hardcoded neutral classes to semantic oklch tokens
- drop unused @tailwindcss/forms, autoprefixer

and Source Structure sections to Flutter AGENTS.md, clarify global vs
feature store placement, and fill gaps in web AGENTS.md (shadcn base-vega
style, constants.ts, no-array-index-key rule, commit conventions).

## Architecture
Next.js 16 landing page for [Frosty](https://frostyapp.io) using the App Router with React 19. Deployed on **Cloudflare Workers** via `@opennextjs/cloudflare`.
### Key Configuration
- **React Compiler**: Enabled in `next.config.ts` for automatic memoization
- **Typed Routes**: Enabled for type-safe navigation (use `Route` type from `next/navigation`)
- **Path Alias**: `@/*` maps to `./src/*`
- **Strict TypeScript**: `noUncheckedIndexedAccess`, `noImplicitReturns`, `noFallthroughCasesInSwitch`, `noImplicitOverride`, `verbatimModuleSyntax`
### Source Structure
- `src/app/` - App Router pages and layouts
- `src/components/` - React components (`ui/` subdirectory for shadcn `base-vega` style — add with `pnpm dlx shadcn@latest add <component>`)
- `src/lib/` - Utilities (`cn()` for className merging, `constants.ts` for external links)
- `src/assets/` - Static images (screenshots)
### Cloudflare Workers
- `wrangler.jsonc` - Cloudflare Workers configuration (bindings, R2, KV, etc.)
- `open-next.config.ts` - OpenNext adapter config (ISR requires uncommenting R2 incremental cache)
- `cloudflare-env.d.ts` - Generated types for Cloudflare bindings (run `pnpm cf-typegen` to regenerate)
- Dev mode calls `initOpenNextCloudflareForDev()` in `next.config.ts` for local Cloudflare emulation
## Naming Conventions
- Components: PascalCase (`Button.tsx`)
- Utilities: camelCase (`formatDate.ts`)
- Hooks: `use` prefix (`useDebounce.ts`)
- Types: PascalCase (`UserProfile`)
## ESLint Rules
Config: `eslint.config.mjs`. Ignores `src/components/ui/`.
Notable strict rules enforced:
- `eqeqeq: 'smart'` - Strict equality (except `== null`)
- `no-console` - Warn on console usage (allows `console.warn` and `console.error`)
- `@typescript-eslint/strict-boolean-expressions` - No implicit boolean coercion (but `allowNullableBoolean` and `allowNullableString` are enabled)
- `@typescript-eslint/switch-exhaustiveness-check` - Exhaustive switch statements
- `@typescript-eslint/consistent-type-imports` - Use `import type` for types (`fixStyle: 'inline-type-imports'`)
- `@typescript-eslint/no-unnecessary-condition` - No redundant conditions
- `@typescript-eslint/no-misused-promises` - Prevent floating promises (`checksVoidReturn.attributes` disabled for JSX)
- `@eslint-react/jsx-shorthand-boolean` - Use shorthand boolean JSX props
- `@eslint-react/no-array-index-key` - Warn on array index as key
- `react-you-might-not-need-an-effect` - Avoid unnecessary useEffect
- Unused variables must be prefixed with `_`
## Commits
Lowercase, no prefixes (e.g., `remove marquee emote background from hero section`). Keep commits tightly scoped.
## Dev Tooling
- **Prettier**: Auto-sorts imports (`prettier-plugin-organize-imports`) and Tailwind classes (`prettier-plugin-tailwindcss`)
- **react-scan**: Runtime render performance visualization (dev only)
