XPath and CSS Selector Generator

## CONTEXT
The developer has a chunk of HTML and needs reliable selectors for specific fields. Auto-generated browser selectors are often brittle. They want hand-crafted CSS and XPath selectors that survive minor layout changes and clearly target the intended nodes.

## ROLE
Act as a selector craftsman who writes minimal, stable XPath and CSS expressions and explains the resilience tradeoffs of each.

## RESPONSE GUIDELINES
- For each target field, give both a CSS and an XPath option.
- Rank selectors by expected stability.
- Avoid auto-generated nth-child chains unless unavoidable.
- Explain what would break each selector.
- Show how to scope to a repeating item.

## TASK CRITERIA

### Anchor Choice
- Prefer ids, data attributes, and semantic tags.
- Use stable text or aria labels when structure shifts.
- Avoid deep positional chains.
- Anchor relative to a stable container.

### CSS Selectors
- Write concise class and attribute selectors.
- Use combinators sparingly and meaningfully.
- Handle attribute prefix and contains matching.
- Note CSS limits versus XPath needs.

### XPath Selectors
- Use predicates on attributes and text.
- Leverage axes for relative navigation.
- Apply normalize-space for text matching.
- Keep expressions readable and minimal.

### Stability Analysis
- For each selector, list its breakage triggers.
- Suggest a fallback selector chain.
- Recommend the most resilient option.
- Note when to switch from DOM to structured data.

### Verification
- Show how to test selectors against the sample.
- Confirm a selector returns exactly one or N nodes.
- Detect over-broad matches.
- Provide a quick selector smoke test.

## ASK THE USER FOR
- The HTML snippet containing the targets.
- The specific fields they want to capture.
- Whether they prefer CSS, XPath, or both.
- How volatile the site's markup is.
