shenleiandClaude Opus 4.8 febfd30f49 feat: A1 短材料复现本单元理解词，并加入黑夜模式 
课程内容
- 重写全部 21 个 A1 单元的听读材料，把本单元理解词织进听/读文本，
  单元内理解词复现率从约 20% 提升到约 77%（各单元 56–96%）。
- 修正 U01 房间号与机场大巴同为 thirty 的撞车（改为 17/30/40）。
- 校验器容差按级别读取（A1 为 8%），materials 覆盖率、字数、
  选项子串等校验全部通过；course_content_test 通过。

黑夜模式
- app_theme 拆分明/暗两套调色板，AppColors 随亮度切换；
  main 用 theme/darkTheme/themeMode + builder 镜像已解析亮度；
  主题偏好持久化到快照；进度页新增“外观主题”切换。

文档
- COURSE-PACK-JSON.md 更新 A1 词池覆盖（840/933）与材料复现约定。

"text": "Ben: OK, Chloe, let's plan this carefully. We have a fortnight in August, and a budget of about fifteen hundred pounds each. That has to pay for transport, accommodation, food, everything.\nChloe: Right. First, getting from London to Edinburgh. I've compared three options. Flying is the fastest, only about an hour, but you have to get to the airport and go through security. The train takes four and a half hours, but it's a direct train, and the views along the eastern coast are lovely. The bus is much cheaper, about thirty pounds, but it takes nearly ten hours.\nBen: Ten hours on a bus? I'd rather not. What about the price of the train?\nChloe: It varies a lot. If we book in advance, it's about fifty pounds. On the day, it can be a hundred and fifty.\nBen: Then let's book now. What about getting around Scotland? Should we hire a car?\nChloe: I've been thinking about that. Public transport is fine between the cities, but the trains to the Highlands aren't very frequent. Some villages have only two buses a day. So for the second week, a car makes more sense. We can split the cost. With fuel, it's approximately forty pounds a day each.\nBen: That's reasonable. And accommodation?\nChloe: In Edinburgh, hotels in the old town are a luxury. They're over two hundred pounds a night in August because of the festival. The alternative is a hostel near the station. It's basic, but the location is perfect. The main reason I like it is we can walk everywhere.\nBen: Fine by me. In the Highlands, I'd rather stay somewhere quiet, maybe a cabin by a lake.\nChloe: I've seen a few. There's one in a regional park, about thirty miles from Inverness. It's not luxury, but it has a kitchen, so we'll save money on food.\nBen: Perfect. Let's write it all down. What's the total?\nChloe: Let me calculate. My rough estimate is about thirteen hundred pounds each, so we can definitely afford it. Hopefully, we could even extend the trip by a day.\nBen: But suppose it rains all week? The weather in the Highlands is totally unpredictable.\nChloe: Then we'll change our arrangements. I'll check the forecast before we depart. Oh, and let's bring some cash. There's often no cashpoint in the small villages, and some places don't take cards, even though the currency is the same.\nBen: Good idea. I'll send you my preference for the dates tonight.",

"text": "Travelling well on a small budget\nMany people think travel is only for the rich. It isn't. With some careful planning, you can see the world without spending a fortune. Here are our top tips.\n1. Be flexible with dates. Prices vary a lot. Flights on Tuesdays and Wednesdays are typically cheaper than at weekends, and hotels by the sea can cost fifty percent less outside the summer. Unless you have school-age children, avoid the holidays.\n2. Book in advance, but not too early. For trains and flights, two or three months before departure is generally the best time. For some low-cost airlines, prices go up sharply in the last few weeks.\n3. Compare transport options. The fastest way isn't always the best. A night bus or train saves you the cost of a hotel. In many countries, the railway is comfortable and relatively cheap, and you arrive in the city center, not at an airport forty minutes away.\n4. Think about location. A cheap room is not a bargain if it's far from everything. If you spend two hours and twenty dollars a day on transport, it makes more sense to pay a little more and stay in a central district.\n5. Try self-service accommodation. Apartments and hostels with kitchens let you cook your own meals. Buy food at local markets. It's cheaper, and you'll meet local people.\n6. Use a travel card. Most big cities have a card that gives you unlimited public transport, and sometimes free access to museums, for a fixed price per day.\n7. Plan a realistic budget. Write down every expense: transport, accommodation, food, tickets, and a little extra for emergencies. Then check it every few days.\n8. Choose your destination carefully. Some coastal resorts depend on tourism and have high prices all year. A nearby town in the same region can be half the price, with a better selection of local restaurants.\n9. Check airport transfers. A cheap flight is not worthwhile if the arrival time is 2 a.m. and the only way into the city is an expensive taxi. Whenever possible, choose flights that arrive during the day.\n10. Pack light. Packing a small bag means you don't pay extra for luggage, and you can move freely wherever you go.\nFinally, remember that the most memorable parts of a trip are often free: a walk along a canal, a sunset from a hill, or a long conversation with a stranger.",

"text": "The Lake District: getting there and where to stay\nThe Lake District is one of the most popular areas in northern England, and it gets very busy in summer. Here's a comparison of your main options.\nGetting there\nBy rail: There are frequent trains from London to Oxenholme, about three hours. From there, change for Windermere. Book in advance for the best prices. There's also an overnight option: a sleeper train with small cabins in each carriage. It's popular with backpackers, and it saves you a night in a hotel.\nBy car: The distance from London is about 270 miles, around five hours. A vehicle gives you freedom, and if you intend to visit several villages, it's the most efficient choice. Otherwise, you'll tend to spend a lot of time waiting for buses. Big groups can hire a van. But parking in the villages is limited, roads are narrow, and phone maps don't always work, so follow the signposts at every crossroads.\nBy bus: The cheapest way, but the journey takes over seven hours, and you usually need to change twice.\nGetting around\nLocal buses connect most towns. They run frequently in summer, but they are less frequent in winter. There's also a lake ferry, which is slow but relaxing. Many visitors hire bikes. Whichever you choose, check the timetable before you go.\nWhere to stay\nThere's a variety of places to stay, from luxury hotels to simple farms, so select one that fits your preference.\nThe Lakeside Hotel: Luxury rooms with lake views, a spa and a restaurant. From £240 per night, breakfast included. Minimum stay: two nights at weekends. Guests can also reserve a table at the restaurant.\nFell End Farm: A family-run farm with four rooms. From £95 per night. Accessible by bus, but the nearest stop is a mile away, and there are no shops nearby, which some guests find inconvenient. Maximum four guests per room.\nWindermere Hostel: Dorm beds from £28, private rooms from £70. Self-service kitchen. Five minutes from the station, so it's a practical choice if you don't have a car.\nOur advice: If you're travelling without a car, stay near a station or a bus stop. You'll save time and money, and you won't miss the last bus home. Check the exact time before you go out. It's unlikely you'll find a room on the day in August, so book early. Whether you choose a hotel or a hostel, a combination of train and bus is the cheapest way to see the whole region.",
