Model x harness x effort registry; bigger top-bar controls

Each entry is now explicitly a model x harness x effort combination:
models/*.json gains harness and effort fields, GPT-5.5 xhigh is
relabeled GPT-5.5 Codex (the harness distinguishes it from GPT-5.5
Pro), and the scrolling marquee is replaced by a readable registry
table (model / vendor / harness / effort / runs, pending rows dimmed)
with an explainer on the model-vs-harness relationship.

Top bar controls enlarged: segmented zh/EN switch and bordered 36px
icon buttons. README rewritten Chinese-first with a hand-maintained
registry snapshot table; README.en.md mirrors it.

+
+One-shot LLM eval cases by NAGI STUDIO: same prompt, different model x harness x effort combinations, one attempt and no retries — a side-by-side record of the runnable artifacts they ship.
+
+**Live site:** https://bench.nagi.fun/
+
+## Models vs harnesses
+
+- **Model**: the weights and inference engine itself — GPT-5.5, Gemini 3.1 Pro, Claude Fable 5.
+- **Harness**: the product/scaffolding wrapping the model — Codex CLI, Cursor, AntiGravity, the Claude web app. It controls tool calls, system prompts, context management and continuation strategy, and often shapes the outcome as much as the model does.
+- The unit of evaluation here is therefore the **combination**: the same model under a different harness or effort level is a separate entry (GPT-5.5 Pro and GPT-5.5 Codex are two records of the same model family). Effort defaults to max; new effort variants of an existing combination can be added later.

+> This table is a hand-maintained snapshot; the site's registry section is generated live from `models/*.json` and is authoritative.
+
+## Structure
+
+```
+outputs/<model-id>/<case-id>.<ext>   raw model artifacts (HTML / SVG), filename = case id
+models/<model-id>.json               combination registry: label / vendor / harness / effort / order / run notes
+site/                                showcase app (Vite + React + Tailwind v4 + GSAP, bun)
+site/src/data/cases.json             case definitions (bilingual prompts, maintainer-owned)
+.github/workflows/                   deploy.yml deploys; ci.yml validates data + builds on PRs
+```
+
+## Development
+
+```bash
+cd site
+bun install
+bun run dev      # syncs outputs/ and serves http://localhost:5173/
+bun run build    # data validation + type-check + build (site/dist)
+```
+
+## Contributing a run
+
+Contributions are data-only — no code changes needed:
+
+1. Artifact: `outputs/<model-id>/<case-id>.<ext>` (e.g. `outputs/gpt-5-5-pro/pelican-cycling.svg`).
+2. Registration: `models/<model-id>.json` (new file for a new combination; add to `runs` for an existing one) — see the schema example in the Chinese README.
+
+CI-enforced rules: dash-only lowercase ids matching the `outputs/` folder name; a **required bilingual provenance `note`** per run (which harness, what effort, one-shot or fixed); every declared run must have its artifact; multiple versions of the same combination x case go in an array with distinct `file` names (e.g. `pelican-cycling-2.svg`).
+
+PRs get data validation + a build from CI; merges to `main` deploy automatically.
