Add pin flow fixes + map pin emoji clipping fix.

• Auth gate now shows an explanatory dialog ("Sign in to publish — it's free...")
  with Cancel / Sign in buttons instead of silently redirecting to the auth
  screen. Users are no longer stranded wondering what happened.
• After signing in and returning to the add flow, state (location, species,
  ripeness, notes) is fully preserved so tapping "Publish pin" again works
  without repeating the 3 steps.
• Species search now matches on Latin name as well as common name — typing
  "plantago" (or any genus/species name) surfaces the right species.
• Community pins now have source: "community" and kind written directly
  on the listing at creation time, so Browse kind filters and layer toggles
  work for user-submitted pins (previously they relied on the joined species
  entity and could be invisible to the "community" layer toggle).
• Map pin emoji (🍎 🌿 🍄 etc.) no longer get clipped at the top. Root
  cause: tall emoji ascenders (🍎's leaf, 🌰's cap) overflowed the top of
  the rasterised marker bitmap. Fix: 6 px of paddingTop on the pin wrap
  gives ascenders headroom; lineHeight set explicitly to prevent Android
  text-layout inflation from shifting glyphs off-centre.

• Browse and In Season (calendar) tabs: horizontal chip / month rows no
  longer stretch vertically when the list below them is sparse (or squash
  when it's full). Root cause: horizontal ScrollViews inside a flex-column
  parent with a FlatList sibling were expanding to fill the column's
  unused height. Fix: flexGrow: 0 + flexShrink: 0 on the scroller.
• Browse filter chips expanded to the full 12-kind set (Pears, Grapes,
  Figs, Flowers, Mushrooms added, already matched the map).

Bug fix on 0.1.2.

• Tapping the bottom preview card now actually navigates to the listing detail
  page. 0.1.2 wrapped the ListingCard (itself a Pressable) in an outer
  Pressable — the inner one claimed the touch but had no handler, so taps
  went nowhere. Fix: pass onPress directly to ListingCard instead of
  nesting.

UX polish on top of 0.1.1.

• Ripeness legend hides when a pin is selected (was overlapping the bottom
  preview card).
• Pin preview card gets a close (×ばつ) button so users can dismiss without
  tapping another pin.
• Preview card shows toxicity badge (⚠ caution) for species with isToxic,
  a description preview line, and a look-alike warning callout when toxic
  species have lookAlikes recorded.
• "tap for details" affordance added to the source attribution row.

Shipped the same day as 0.1.0 — fixes all the things that were half-plumbed when
seeded open-data pins landed in the app for the first time.

Map

• Pin rings now reflect ripeness (the legend actually matches the pins). Marker
  keys include ripeness bucket so cached views don't swallow updates.
• Cluster bubbles take the average ripeness of the pins they cover — zoomed-out
  views now show a useful "what's ripe here" heat gradient instead of all-green.
• Kind emoji on each pin (apple 🍎, berry 🫐, citrus 🍊, nut 🌰, etc.) —
  previously every imported pin rendered as 🌿 because only community pins had
  a linked species.
• Filter chips expanded to all 12 catalog kinds (added pears, grapes, figs,
  flowers, mushrooms).

Data

• Seeded listings now link to species entities in InstantDB (deterministic
  IDs mean this is idempotent on re-seed). Species photos, seasonality, toxicity
  warnings, and look-alikes now surface on imported pins just like community ones.
• New kind field denormalised onto every listing — lets the map filter by
  category without forcing a server-side join.
• Ripeness computed per-listing from species seasonMonths ×ばつ current month
  at seed time. April re-seed result for Nevada County's 3,603 pins:
  604 ripe (bay laurel, citrus, loquat, dandelion, spring greens), 294 soon,
  377 forming, 2,328 unripe.

Listing card

• Source attribution badge (dot + "via iNaturalist" etc.) on every card.
• Kind emoji fallback when a species photo isn't available — no more blanket
  🌿 for imports.
• Season strip only renders when the species has a season — cleaner card for
  sparse imports.

First public preview. Everything you need to try the app and start dropping pins.

App

• React Native + Expo SDK 51 scaffold with file-based routing (Expo Router v3)
• Core screens: Map (clustered), Listing detail, Add flow, Browse, Calendar, Profile, About, Onboarding
• Google Maps integration with a custom paper-textured style (and a dark variant)
• Privacy-first: coordinates fuzzed to ~110m on community pins
• Ripeness ring math (14-day half-life) blends species seasonality with community confirmations

Data

• InstantDB realtime backend, no custom server
• source-tagged listings render as toggleable map layers with per-source pin colors
• Open-data aggregator npm run seed:listings pulls from iNaturalist, GBIF, OpenStreetMap, Falling Fruit, and SF/NYC/Portland street-tree inventories
• Weekly GitHub Action re-syncs stale open-data pins
• Seed catalog of ~85 edibles — worldwide staples plus Sierra Nevada + California natives (manzanita, toyon, oaks, elderberry, bay laurel, pine nuts)
• Nevada County, CA seeded with 3,198 iNaturalist + GBIF pins on first run

Builds

• EAS preview profile producing installable Android APK + iOS simulator bundle
• Release pipeline (GitHub Actions) attaches APK + iOS bundle to every tag
• Weekly sync-data.yml refresh workflow

Meta

• AGPLv3 — non-negotiable, protects the community data from closed forks
• Agent-friendly docs (AGENTS.md, CLAUDE.md, .cursorrules, copilot-instructions.md)
• GitHub Pages marketing site with generated OG image
• Foraging ethics, privacy policy, security policy, code of conduct, governance
