 "milestones": [
  {
   "operator": "generate",
   "request": "We're launching a tech news site called \"Zhiyuan Express\"; let's get the homepage to a viewable, usable state first.\n\nAt the top put the site name \"Zhiyuan Express\" and a subtitle \"10 minutes a day to understand the tech world\". Below is the channel navigation, six items in this order: All, AI Frontier, Chips, Open Source, Security, Venture Capital, with \"All\" selected by default, and the selected one must be obvious at a glance. Next to the nav, give a sort toggle with two options \"Latest\" and \"Hottest\", default \"Latest\".\n\nThere are 45 articles in total; the list shows 12 per page, with pagination below (Previous / Next + current page number, formatted like \"Page 1 / 4\"). Each card must show: title, channel name, author, publication date, and read count; the few I marked \"Featured\" need a Featured badge.\n\nThe first 10 are hand-written by editors; I'll list them in the order I thought of, don't mix them up:\nNo. 1 \"Domestic LLM Platforms Slash API Prices by 80% at Once\", AI Frontier, by Lin Yan, 5120 reads, featured;\nNo. 2 \"3nm Capacity Hit by Another Buying Frenzy — Next Year's Orders Already Full\", Chips, Zhou Xia, 3980;\nNo. 3 \"Open Source Foundation Gets a New Leader, Who Wants to Cut Half the Projects\", Open Source, He Zhiyuan, 2760, featured;\nNo. 4 \"An Overlooked Firmware Flaw Affects 20 Million Routers\", Security, A Lan, 4310;\nNo. 5 \"Early-Stage Funds Start Backing AI Companions, Valuations Soar Absurdly\", Venture Capital, Shen Miao, 1890;\nNo. 6 \"The Energy-Efficiency Race for Edge Inference Chips Enters the Second Half\", Chips, Zhou Xia, 2240;\nNo. 7 \"We Trialed 12 AI Writing Tools — The Conclusion Was a Bit Surprising\", AI Frontier, Lin Yan, 6480, featured;\nNo. 8 \"The Open Source License Dispute: This Time It's Datasets\", Open Source, He Zhiyuan, 1530;\nNo. 9 \"Three Years of Zero Trust in Practice: Five Pitfalls Enterprises Have Fallen Into\", Security, A Lan, 990;\nNo. 10 \"Consumer Robot Funding Overtakes Industrial Robots for the First Time\", Venture Capital, Shen Miao, 2050, featured.\n\nThe remaining 35 are backlog pieces; I won't write them out one by one, fill them in by rule to 45: titles go \"Zhiyuan Observer No. 011\" through \"Zhiyuan Observer No. 045\" (numbers zero-padded to three digits), authors all \"Editorial Desk\"; channels starting from No. 11 cycle in the order AI Frontier, Chips, Open Source, Security, Venture Capital (No. 11 is AI Frontier); read counts, to keep it simple, are the number times 37; these 35 are all not featured.\n\nDates run backwards one per day: No. 1 is the newest at 2026-04-14, each subsequent number is one day earlier, all the way to No. 45, which is exactly 2026-03-01. The default \"Latest\" sort is this order from No. 1 to No. 45; clicking \"Hottest\" re-sorts by read count, highest to lowest. Keep the overall style clean — white background, one blue as the accent color is enough."
  },
  {
   "operator": "add section",
   "request": "A list alone is still flat; ops wants two things.\n\nFirst, add a \"Today's Trending\" block, placed for now directly above the article list, spanning the full row, with five slots side by side horizontally, labeled ranks 1 to 5, each showing the article title and read count. The rule: the trending list follows the currently visible results — whichever channel is selected and whatever is searched, the trending list picks only the 5 highest-read articles from that batch, unaffected by pagination (page 2 shows the same trending list as page 1). This block is ops's storefront, so it must be eye-catching. If there are currently no articles at all, the trending slot must show a message like \"No trending articles\", not a blank box.\n\nSecond, add a search box in the nav row; typing a term filters by whether the title contains it, stacking with the channel filter (both conditions must hold), and after searching it automatically returns to page 1. When nothing is found, the list area must have a clear empty-state message, and the pagination control must not still show page 2.\n\nOne more reader request: clicking an article title marks that piece as \"Read\"; read cards fade and carry the word \"Read\"; next to the site name show \"Read N articles\", starting at 0. Note that clicking the same piece repeatedly must not increase the count, nor turn it from read back to unread. Read state follows the article: switching channels, paging, or searching and then clearing the search must leave previously marked pieces still read."
  },
  {
   "operator": "restructure layout",
   "request": "The homepage information is too scattered; do a layout revision.\n\nOn wide screens switch to two columns: left (main area) is the article list and pagination, right is a narrow column; move \"Today's Trending\" from above the list into this right column, stacked vertically ranks 1 to 5; the right column's trending list must remain visible as the page scrolls. Merge the channel nav and search box into one sticky bar that stays pinned to the top as you scroll down, so channels can be switched at any time.\n\nOn narrow screens (phones) don't force two columns — go back to a single vertical column, move the whole trending block below the article list, not a single piece of content fewer, and pagination still works.\n\nRedesign or not, none of the existing things may be lost: channel filtering, search, sorting, pagination, the Featured badge, read fading and the \"Read N articles\" count, and the trending list following filters and search — behavior exactly as before the redesign. Put the pagination control at the bottom of the main-area list; on page 1 \"Previous\" must be unclickable, and likewise \"Next\" on the last page."
  },
  {
   "operator": "restyle",
   "request": "Finally, the theme. Put a theme toggle at the top of the page that switches between \"Light / Dark\", and the toggle must show which mode is current.\n\nIn dark mode the whole site's background and text invert, easy on the eyes. But don't just paint the background black and call it done — the visual signals established earlier must still hold in dark mode: the Featured badge must be recognizable, read cards must be clearly weaker than unread ones, and the top three trending ranks must be distinguishable from ranks 4 and 5.\n\nAlso unify the accent color: channel selected state, current page number, trending rank, and Featured badge use the same accent set, one set per mode — don't leave old blue blocks from the previous version stranded in the dark. For overall tone I want restraint and cleanliness, not a screen full of clashing high-saturation colors — but the trending list must remain the page's focal point; find that balance yourself and keep the trade-off consistent site-wide.\n\nSwitching themes must not wipe the current state: selected channel, search term, sort, current page, which articles are read, and the read count must all be exactly as they were when switching over and back."
