 "title": "Alley Corner community home-service booking site: build from scratch, night redesign, and checkout",
 "milestones": [
  {
   "operator": "generate",
   "request": "The new project is called \"Alley Corner\", a community home-service booking site, desktop-first — build the whole site from scratch.\n\nA top nav: on the left the site name \"Alley Corner\" plus a small line \"Things at your doorstep — leave them to Alley Corner\", in the middle a search box (searching by service name or shop name is fine), on the right a \"My bookings\" entry with a numeric badge showing how many services are currently in the list; when the list is empty the badge must not show.\n\nThe homepage is laid out top to bottom like this: first a hero banner, the big slogan \"Things at your doorstep — leave them to Alley Corner\", with a line of small text below \"Cleaning · Repairs · Nails · Pets · Errands — at your door within an hour\"; next a horizontal \"Flash sale\" card row with 6 services, each card showing both the limited-time price and the struck-through original price, each with a \"Grab\" button that adds straight to my booking list (charged at the limited-time price); below that, the main service list.\n\nThe list needs filters and sorting above it. Six categories: Cleaning, Appliance repair, Repair & installation, Nails & lashes, Pet services, Errands; four areas: Chaoyang, Haidian, Xicheng, Fengtai; three sorts: Recommended (by monthly orders high to low), Price low to high, Rating high to low, defaulting to Recommended. The list holds 12 per page, with the pager below the list. Each card must have service name, shop, unit price (how much per hour), rating, monthly orders, area, plus an \"Add to booking\" button. Clicking the same service repeatedly must not add a second row — just show a notice that it's already in the list, and the badge number must not go up either.\n\n\"My bookings\" lists service name and unit price row by row; each row can be deleted, and at the bottom there's a total (the sum of the rows' unit prices). When the list is empty there must be an empty state reading \"No services selected yet — go pick one\"; when a search finds nothing there must also be an empty state reading \"No matching services\".\n\nThe data is what the ops colleague tossed over, 42 entries in total; I'll paste a few for you, fill in the rest the same way, just make the names sound plausible: Auntie's Here · 3-Bedroom Deep Clean 98/hour 4.9 1280 monthly orders Haidian can be urgent; CleanNest · Daily Wipe-Down 68 4.6 860 Chaoyang can be urgent; Jiebang · Sofa & Carpet Cleaning 128 4.7 430 Xicheng cannot be urgent; Old Zhang Appliances · Range Hood Deep Clean 168 4.8 2130 Chaoyang can be urgent; Elec Er · AC Refrigerant & Relocation 138 4.5 970 Fengtai can be urgent; Quickhand Wang · Drain Unclogging 158 4.4 610 Xicheng can be urgent; Screwdriver · Furniture Assembly 88 4.6 520 Haidian cannot be urgent; Fingertip Garden · At-Home Manicure 158 4.9 340 Chaoyang cannot be urgent; Lash Whisper · Lash Extensions 198 4.8 210 Haidian cannot be urgent; Paw Pal · Pet Bath & SPA 200 4.7 180 Chaoyang can be urgent; Meow Planet · At-Home Pet Feeding 60 4.9 760 Haidian can be urgent; Courier Lao Li · Same-City Pickup & Delivery 40 4.3 3050 Chaoyang can be urgent; Golden Hand · Rosewood Furniture Care 298 4.6 90 Xicheng cannot be urgent (this one goes under Repair & installation).\n\nThe counts have to match: Cleaning 10, Appliance repair 8, Repair & installation 5, Nails & lashes 6, Pet services 6, Errands 7; by area Chaoyang 14, Haidian 12, Xicheng 9, Fengtai 7. Pets hasn't been rolled out in Fengtai yet — not a single one there. Prices all fall between 40 and 298; the cheapest is Lao Li's 40, the most expensive is Golden Hand's 298; the best seller is Lao Li's at 3050, second best is Old Zhang Appliances' 2130 — for the data you fill in, monthly orders must not exceed 2130 and must not be below 50.\n\nThe flash sale slots hold these 6: CleanNest · Daily Wipe-Down, Elec Er · AC Refrigerant & Relocation, Quickhand Wang · Drain Unclogging, Screwdriver · Furniture Assembly, Paw Pal · Pet Bath & SPA, Courier Lao Li · Same-City Pickup & Delivery. The limited-time price is 30% off the original, with odd cents dropped (i.e. just cut off the decimal part, no rounding)."

  {
   "operator": "restyle",
   "request": "Before launch the style needs a refresh. This version is too bright and white — we want to go night-toned: dark background across the site (near-black dark gray), primary color switched to warm orange, body text in light colors, cards as dark blocks slightly brighter than the background. Buttons, badges, the filter selected state, and the current page in pagination are all pointed out with this warm orange, while everything else unselected stays dark neutral. Be restrained — don't turn it into the multicolored look of an e-commerce sales event; the whole site is threaded through by this one primary color.\n\nA new skin is a new skin, but don't mess up what the previous version built — the list is still 12 per page, the default is still sorted by monthly orders, the badge's \"repeated adds don't increase\" logic stays the same, and no field on the cards is lost; the empty states must turn dark too, don't leave a glaring white block in the page."
  },
  {
   "operator": "remove section",
   "request": "Product isn't going to continue with the flash sale gimmick — remove the whole \"Flash sale\" horizontal row on the homepage, together with its heading, and don't leave a hole in the page; the content below moves up accordingly.\n\nBut the discount can't disappear along with it: the 6 services that were in the flash sale slots should be marked directly on the list cards as discounted (state clearly that it's 30% off), with the price showing the discounted number (same algorithm as before: 30% off, odd cents dropped), and adding to the booking list charges the discounted price too. The tag must be noticeable so users can tell at a glance who's discounted, but don't make a mess of the overall tone we just settled on.\n\nAlso, the total list count and the counts per category and per area must not be affected; price sorting must also sort by the discounted prices."
  },
  {
   "operator": "make interactive",
   "request": "Finally, wire up the checkout flow end to end.\n\nFirst, in the booking list, each row can choose a service duration of 1 to 4 hours; services marked as not urgent must not be given an urgency option, while urgent-capable ones get a toggle.\n\nClicking \"Book now\" goes through three steps: step one reviews the service, duration, and urgency, and can still change them here; step two fills in contact name, phone number, door address, and desired time slot; step three is the bill breakdown plus submit. There must be a step indicator showing which step you're on, the ability to go back to the previous step, and what you've filled in or selected must not be lost.\n\nHow the money is calculated, so we're clear: throughout, \"drop the odd cents\" means cutting off the decimal part directly, no rounding: each row first takes unit price × duration; a row of 3 hours or more gets 10% off first, with odd cents dropped; if that row has urgency checked, add 15% on top of the discounted integer, and drop the odd cents again. The rows add up to the subtotal. The first-order coupon takes 30 off orders of 200 or more, applied only once to the whole order, checked by default for the user, and they can also uncheck it. If the final amount is under 99, add a 15 basic service fee. The breakdown must list everything clearly so users can understand every line.\n\nIn step two the phone number must be 11 digits and the address must not be empty; if they're not filled in correctly, don't let the user proceed, and show a notice. After submitting, show a success page with an order number, clear the list, and reset the badge to the empty state. Clicking the submit button several times by accident must not create several orders."
