Antigravity Build Guide

COPYI am building a shared trip planner web app called "Bali Trip" for 5 travelers. I have attached: 1. My Figma design export files (HTML/CSS) — read these to understand the full design system, component styles, colours, typography, and spacing. Do not build anything yet. 2. Design screenshots (Images 1–15) — reference map is below. 3. My credentials file. IMAGE REFERENCE MAP: Image 1 = Add Expense form Image 2 = Add Flight form Image 3 = + Add Menu Modal Image 4 = Add to Itinerary form Image 5 = Add to Wishlist form Image 6 = Edit Itinerary item form Image 7 = Flight Status detail Image 8 = Activity/Place Detail view Image 9 = Itinerary Timeline (main view) Image 10 = Login / User Selection screen Image 11 = Expenses overview + settlement Image 12 = Map view with filter bar Image 13 = Move Wishlist item to Itinerary Image 14 = Wishlist item detail card Image 15 = Wishlist list view TECH STACK: React + Tailwind CSS, Supabase (database + realtime + edge functions). TRIP CONSTANTS (hardcode these everywhere): - Trip name: Bali Trip - Dates: 11 April 2026 to 15 April 2026 (5 days) - Travelers: Andrew (MYR), Carol (MYR), Wei2 (MYR), Mayvipah (THB), Chaaanok (THB) - Default travel mode: Car / Driving only. No scooter, no walking options anywhere. - All prices entered in IDR. Displayed as "Rp 150.000" format. - No $ signs, no price tier symbols ($$$ etc) anywhere in the app. SUPABASE CREDENTIALS: URL: [paste your URL] Anon Key: [paste your anon key] YOUR TASK FOR THIS SESSION: 1. Set up the React + Tailwind project connected to Supabase 2. Run this exact SQL schema in Supabase — do not modify any field names: CREATE TABLE users ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), name text NOT NULL, currency text NOT NULL, pin_hash text, created_at timestamptz DEFAULT now() ); CREATE TABLE fx_rates ( id serial PRIMARY KEY, base text NOT NULL, target text NOT NULL, rate numeric NOT NULL, fetched_at timestamptz DEFAULT now() ); CREATE TABLE itinerary_items ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), name text NOT NULL, address text, opening_hours text, cost_idr integer, image_url text, category text, status text DEFAULT 'wishlist', trip_day integer, start_time time, duration_mins integer, sort_order integer, source_url text, is_time_block boolean DEFAULT false, time_block_label text, is_done boolean DEFAULT false, added_by uuid REFERENCES users(id), created_at timestamptz DEFAULT now() ); CREATE TABLE votes ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), item_id uuid REFERENCES itinerary_items(id) ON DELETE CASCADE, user_id uuid REFERENCES users(id), UNIQUE(item_id, user_id) ); CREATE TABLE activity_attendance ( item_id uuid REFERENCES itinerary_items(id) ON DELETE CASCADE, user_id uuid REFERENCES users(id), PRIMARY KEY (item_id, user_id) ); CREATE TABLE comments ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), item_id uuid REFERENCES itinerary_items(id) ON DELETE CASCADE, user_id uuid REFERENCES users(id), text text NOT NULL, created_at timestamptz DEFAULT now() ); CREATE TABLE expenses ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), description text, amount_idr integer NOT NULL, paid_by uuid REFERENCES users(id), split_between uuid[] NOT NULL, category text, created_at timestamptz DEFAULT now() ); CREATE TABLE flights ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), user_id uuid REFERENCES users(id), flight_number text, airline text, departure_date date, departure_time time, terminal text, gate text, data_json jsonb, last_updated timestamptz DEFAULT now() ); CREATE TABLE accommodation ( id uuid PRIMARY KEY DEFAULT gen_random_uuid(), property_name text, address text, checkin_time timestamptz, checkout_time timestamptz, host_name text, host_phone text, updated_by uuid REFERENCES users(id), updated_at timestamptz DEFAULT now() ); ALTER PUBLICATION supabase_realtime ADD TABLE itinerary_items; ALTER PUBLICATION supabase_realtime ADD TABLE expenses; ALTER PUBLICATION supabase_realtime ADD TABLE votes; ALTER PUBLICATION supabase_realtime ADD TABLE activity_attendance; ALTER PUBLICATION supabase_realtime ADD TABLE comments; 3. Seed the 5 users: INSERT INTO users (name, currency) VALUES ('Andrew', 'MYR'), ('Carol', 'MYR'), ('Wei2', 'MYR'), ('Mayvipah', 'THB'), ('Chaaanok', 'THB'); 4. Show me the 5 user UUIDs from the users table after seeding. 5. Do NOT build any UI components yet. Confirm when done and show me the UUIDs.

COPYFX cron is working. This is the final polish session before launch. Go through the entire app and fix the following: 1. DESIGN CONSISTENCY: - Every screen must match the Figma designs I uploaded (Images 1–15) - Font sizes, spacing, card shadows, border radii, colours must be consistent throughout - Bottom nav bar style must be identical on every tab - All prices must show "Rp X.XXX" format (dot as thousands separator) — never "$" or "IDR X,XXX" - No placeholder "Coming soon" text should remain anywhere 2. MOBILE RESPONSIVENESS: - Test every screen at 390px wide (iPhone 14 viewport) - Nothing should overflow horizontally - All tap targets minimum 44px height - Bottom nav must not overlap content 3. REALTIME SYNC CHECK: - Confirm Supabase Realtime subscriptions are active on: itinerary_items, expenses, votes, activity_attendance, comments - When any user adds/changes data, other users see it within 2 seconds without refresh 4. EDGE CASES TO HANDLE: - Empty state on Timeline: "No plans yet for Day X — add from Wishlist or use the + button" - Empty state on Wishlist: "No saved places yet — tap + to add your first" - Empty state on Expenses: "No expenses yet — tap + to log your first" - Empty state on Flights: each row shows "Add flight" prompt - GPT lookup failure: shows manual entry form with toast notification - AviationStack failure: shows "Flight status unavailable — check airline app" - No internet: show "You're offline — showing last saved data" 5. NAVIGATION WIRING: - "View in Timeline/Wishlist" from map opens correct tab + scrolls to correct item - "Add to Wishlist" from + modal opens Wishlist form - "Add to Itinerary" from + modal opens Itinerary form - "Add Expense" from + modal opens Expense form - "Add Flight" from + modal opens Flight form - All back arrows navigate correctly 6. FINAL CHECK — run through this full user flow once: - Login as Andrew → add a place to Wishlist → vote on it → move it to Itinerary Day 2 → check the timeline → mark it Done → add an expense → check settlement → add a flight → view flight status - Everything should work end to end with no errors in console
