# Feature library ("What's here")

Airbnb-amenities pattern: a **curated library** of features, each with a fixed
icon + label + slug. Operators pick **up to 15** for their attraction.
Free-text is not allowed — it keeps icons consistent, data filterable, and
listings honest.

## Display
- **Detail page:** a tile grid in the weather-card style (icon above, label
  below). First **10** show; the rest behind a "+ N more" expander tile.
- **Cards/search:** only the 2–3 most decision-critical (buggy, indoor, free)
  appear on cards; the full set lives on the detail page.
- **Operator picker:** grouped by category, tap to toggle, live
  "12 of 15 chosen" counter; at 15 the picker refuses until one is removed
  (choosing is prioritising). See `edit.html` for the working design.

## Rules
- **Cap: 15 per attraction**; detail page shows 10 + "+ N more" expander.
- Library is **versioned and curated** — operators request additions, they
  don't self-serve (prevents icon drift + junk).
- "Filter?" column: ✅ core = one of the 10 primary filters today (backed by
  the existing boolean columns); v1.5/v2 = promoted into "More filters" as
  data coverage grows. **SEND features are the planned differentiator**
  (Maya persona) — surface them prominently once coverage justifies it.

## Data model
- `attraction.features` = array of slugs (≤15), validated against the library.
- The 6 existing boolean columns (indoor/outdoor/buggy/baby-changing/parking/
  free) stay as first-class filter columns; their matching library slugs are
  auto-synced both ways so filters and tiles never disagree.
- **Import contract:** `features` column = pipe-separated slugs, e.g.
  `cafe|picnic|toilets|party-room|animal-feeding`. Unknown slugs are flagged
  for curation, not silently dropped. See `docs/product/import-contract.md`.
