# webflow Surface — Frontend Evidence

**Domain evidence** and shared workflow doctrine for browser/Webflow frontend work. This surface owns the implement -> debug -> verify phases through the workflow references below, and acts on the evidence gathered here when the hub detects a Webflow surface. Detection markers: `src/2_javascript`, `webflow`, `--vw-` custom properties, CDN-delivered client scripts.

## 1. WHEN THE HUB BUNDLES THIS

- The task touches Webflow-published pages, CDN-delivered `webflow.js`/client scripts, or `src/2_javascript` sources.
- The active workflow phase needs frontend standards (CSS/HTML/JS), an implementation pattern, a performance remediation, a deployment step, or a browser debugging/verification procedure.
- This surface owns edits, tests, and verification through the workflow references; hand off formal findings-first review to `code-review` and author-side quality gates to `code-quality`.

---

## 2. REFERENCE MAP

Language standards (load the detected language's trio; a frontend task legitimately spans all three):

Workflow: the implement -> debug -> verify phases are covered by the split implementation, debugging, and verification resources above; no root-level workflow trio is assumed.

## 2b. SMART ROUTING (machine-readable)

This block is the deterministic projection of code-webflow's own reference/asset routing; keep it in sync with the parent hub union.

```python
# code-webflow owns its intent -> reference/asset routing. Paths are relative to
# this skill root. The parent sk-code hub RESOURCE_MAP is the union of this map
# (re-prefixed with sk-code-webflow/) and the sibling code-opencode map plus the
# parent-owned universal/shared tier; a drift guard enforces that equality.

## 3. SURFACE STANDARDS (the non-negotiables)

- **CDN runtime reality.** Client scripts ship over a CDN with cache lag; treat every deploy as versioned and verify the minified runtime, not just the source. See `references/deployment/minification-guide/overview-terser-and-patterns.md` and `references/verification/verification-workflows/gate-and-automated-options.md`.
- **Interaction-gated loading.** Heavy vendors (HLS.js, FilePond, Swiper) load on interaction/visibility, never eagerly. See `references/performance/interaction-gated-loading.md` and `references/implementation/observer-patterns/mutation-and-intersection.md`.
- **Core Web Vitals are a gate, not a report.** LCP/CLS/INP regressions block; remediate against `references/performance/cwv-remediation.md` and `references/performance/webflow-constraints.md`.
- **Focus and forms are accessibility-load-bearing.** Focus traps and upload flows follow `references/implementation/focus-management/selector-and-focus-trap.md` and `references/implementation/form-upload-workflows/overview-architecture-and-filepond.md`.

---

## 4. ASSETS (on-demand, deferred from the first slice)

- Integrations, patterns, templates, scripts — `assets/integrations/`, `assets/patterns/`, `assets/templates/`, `assets/scripts/`
- Surface checklists — `assets/webflow-debugging-checklist.md`, `assets/webflow-verification-checklist.md`

Assets are pulled on demand by the active workflow phase; they are not part of the initial evidence slice.
