   "request": "We're launching a community local-services site, called 'Xiangkou Life'. Fix the city as 'Linjiang' for now and show it next to the brand name. The first screen is all about finding a provider: a brand bar with a search box on top (substring match on provider name is fine — partial input should find matches), below it category filters (All / Cleaning / Repairs / Errands / Care), area filters (All / East Side / West Side / Old Town / Jiangbei), and a sort dropdown: the default 'Comprehensive' sorts by order count high to low; the other two are 'Price: low to high' and 'Rating: high to low'. For tied ratings, put the one with more orders first; for tied prices, put the higher rating first. Show 9 providers per page, with page numbers below that can be clicked to page through. Above the list there should be a result count written as 'X providers in total', updating after filtering. Each provider gets a card showing name, category, area, starting price (prefixed with ¥), rating and order count, and it must be obvious at a glance whether they can be booked today. If a filter leaves nothing, don't leave a blank — show 'No providers match — try different filters'.\n\nOps sent over a rather messy roster; let me copy it down, around forty providers, don't miss any:\nCleaning — Sister Li Home Services (East Side, 89, 4.8, 1203 orders, available today); Clean Home (West Side, 99, 4.6, 876, available); A-Zhen Hourly Cleaning (Old Town, 68, 4.9, 1544, not available today); Blue Sky Cleaning (Jiangbei, 119, 4.5, 402, available); Wan Jia Clean (East Side, 79, 4.7, 991, not available today); Xiao Lin Window Cleaning (West Side, 59, 4.4, 318, available); Qingchuan Home Services (Old Town, 129, 4.9, 1330, available); Neighborhood Help Cleaning (Jiangbei, 88, 4.3, 245, available); Fresh Everyday (East Side, 109, 4.6, 655, not available today); Auntie Wang Deep Clean (Old Town, 159, 4.8, 720, available); LOHAS Mite Removal (Jiangbei, 139, 4.2, 180, available).\nRepairs — Old Zhang Appliance Repair (Old Town, 49, 4.7, 2100, available); A-Bin Air Conditioning (East Side, 129, 4.8, 1460, available); Plumbing & Electrical Rapid Repair (West Side, 79, 4.5, 980, available); Jiangbei Pipe Unclogging (Jiangbei, 69, 4.4, 610, not available today); Bright Locksmith (East Side, 99, 4.6, 530, available); Xiao Chen Phone Repair On-Site (West Side, 39, 4.3, 1720, available); Thermostat Water Heater (Old Town, 149, 4.9, 460, available); All-Round Home Repair (Jiangbei, 89, 4.5, 1180, available); Old Zhou Lighting Installation (East Side, 59, 4.2, 275, not available today); Washing Machine Doctor (West Side, 109, 4.7, 840, available); Door & Window Repair King (Old Town, 119, 4.1, 150, available).\nErrands — Flash Courier A-Jun (East Side, 15, 4.6, 3200, available); Old Town Express (Old Town, 18, 4.5, 2450, available); Jiangbei Errands (Jiangbei, 22, 4.3, 890, available); Westside Urgent Delivery (West Side, 25, 4.7, 1560, not available today); Queue Whiz (East Side, 35, 4.4, 470, available); Night Errand Team (Old Town, 45, 4.8, 320, available); Medicine Pickup (West Side, 28, 4.9, 1090, available); Document Courier (Jiangbei, 32, 4.2, 640, available); Fresh Grocery Pickup (East Side, 19, 4.5, 1875, not available today); Pet Transport Errands (Old Town, 55, 4.6, 260, available).\nCare — Warm Sun Companionship (West Side, 199, 4.9, 540, available); Nanny Zhang (East Side, 259, 4.8, 410, not available today); Senior Bath Assistance (Old Town, 169, 4.7, 230, available); Night Bedside Care (Jiangbei, 229, 4.6, 310, available); Rehab Massage Home Visit (West Side, 189, 4.5, 620, available); Postpartum Care (East Side, 299, 4.9, 175, available); Pet Feeding Home Visit (Old Town, 79, 4.4, 980, available); Dog Walking Butler (Jiangbei, 49, 4.3, 1420, available); Post-Surgery Care (West Side, 209, 4.2, 140, not available today); Medical Escort & Appointment Booking (East Side, 149, 4.8, 760, available).\nDon't build the ordering flow yet — this version just needs to make finding a provider smooth. Keep the overall style clean, with a light background, not too busy."

  {
   "operator": "restructure layout",
   "request": "Users say the filter bar piled up at the top is too cramped — it's fine on mobile, but on desktop you can't see many providers on one screen. Change the layout: on wide screens, move all four control groups (search box, category, area, sort) into a fixed filter column on the left (move the search box over too — no search in the brand bar anymore), leaving the right side for the results list; make the brand bar sticky so it stays on top when scrolling, so people can always see the brand and the city. Also, users often can't remember what they've filtered, so above the results area list each currently active condition (the current search keyword counts as one too); each can be dismissed individually, and dismissing the keyword chip is equivalent to clearing the search while leaving the other conditions untouched; next to that add 'Clear all' — to be clear, 'Clear all' only clears the filter conditions and the search keyword, and keeps the user's current sort choice, don't reset that for them. Another old bug: after going to page 3 and then changing a filter, the page number stays on page 3 and looks like there are no results — after changing a filter, go back to page 1. This is a layout move, so don't mess up the numbers and rules from the previous version: the count, sorting rules, 9 per page, and paging must all stay exactly the same."
  },
  {
   "operator": "add section",
   "request": "Time to take bookings. Clicking 'Book' on a card opens a three-step booking flow: step 1, pick a visit time slot — morning, afternoon or evening; one must be selected to go on. Step 2, enter the service duration, which can only be between 1 and 4 hours — outside that range it can't be entered/selected — and decide whether to add 'Rush today'. Step 3 is the confirmation page, spelling out the provider name, the selected slot, how many hours, how the fee was calculated (starting price × hours, how much the rush added, how much was discounted) and the final amount to pay, with a 'Confirm booking' button at the bottom. The money math has been checked with finance: starting price × hours, plus 20 if rush, then if the result is 200 or more subtract 30; ignore the decimals — everything is in whole numbers. For providers who can't be booked today, the booking entry on the card must not be clickable, and naturally rush doesn't apply. After booking, the provider's card should keep a 'Booked' marker, and the top should show a 'My bookings' number, incremented by one per completed booking; 'Booked' is just a marker — the booking entry stays, and the same provider can be booked again, incrementing the number again. If the user changes filters or pages away and comes back, the marker and the number must still be there. Users misclick all the time, so clicking 'Confirm booking' several times on the confirmation page must count as only one booking. The booking button and the 'Booked' marker must stand out, so people can see at a glance whom they've booked."
  },
  {
   "operator": "restyle",
   "request": "The brand has settled on a new direction: turn the whole site into a night look — dark background, light text — and add a toggle in the brand bar to switch back and forth between the day and night skins. The style requirement is restrained and minimal, not garish; the site keeps a single accent color, used consistently from start to finish wherever something needs to catch the eye. Status indicators like bookable/not bookable may use a little color of their own, but only on the status indicator itself — don't let it spread elsewhere. When reskinning, be careful not to break what previous versions built: the left/right split, the sticky brand bar, condition chip dismissal and clearing, the count and pagination all stay as they are, and how many providers have been booked and how much was quoted must not change; under the night look you must still be able to tell at a glance who can be booked today and who can't, and text must not smear into the background."
