We need to produce an article about "大型网页建设全攻略，从规划到上线的关键要点". Must be 1500+ characters (words? It says 字数要求：必须写满1500字，不能少于1050字！ So need at least 1050 characters (Chinese characters). Must be 6-8 paragraphs, each 150-250 Chinese characters. Must start with a sentence that echoes the title and introduces the topic. Then expand. End with a conclusion that echoes the title. No title at the top (they said "直接输出正文，不要标题"). So just the article body. Must be natural, conversational tone. Avoid AI filler words. Use specific details, short sentences, active voice.

We need 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs, each ~180 characters. That gives about 1260 characters, but need at least 1050 characters, so okay. Actually requirement "必须写满1500字" meaning must reach 1500 characters? They say "必须写满1500字，不能少于1050字！" This is contradictory: "必须写满1500字" means must fill 1500 characters (words?), but cannot be less than 1050. Probably they want at least 1050 characters, but want to fill 1500? Usually they want at least 1500 characters, but they also say can't be less than 1050. So we need to produce at least 1500 Chinese characters. Let's target around 1600 characters to be safe.

We need 6-8 paragraphs, each 150-250 characters. If we have 7 paragraphs of ~230 characters each, total ~1610 characters. That satisfies.

Let's craft 7 paragraphs.

Paragraph 1: Opening, echo title, introduce topic. ~200 characters.

Paragraph 2: Planning stage details: requirement gathering, target audience, site map, wireframes. ~200 chars.

Paragraph 3: Design stage: UI/UX, visual identity, responsive layout, prototype testing. ~200 chars.

Paragraph 4: Development stage: architecture, tech stack, modular coding, version control, performance optimization. ~200 chars.

Paragraph 5: Content creation: copywriting, SEO basics, image optimization, accessibility checks. ~200 chars.

Paragraph 6: Testing and launch prep: QA, cross-browser, load testing, staging environment, rollback plan. ~200 chars.

Paragraph 7: Launch and post-launch: monitoring, analytics, iteration, maintenance. ~200 chars, concluding echo title.

Each paragraph 150-250 characters. Let's write each about 200 Chinese characters.

We must avoid AI filler words like "、". Use natural flow.

Let's count approximate characters.

Paragraph 1: "大型网页建设全攻略，从规划到上线的关键要点" is title, but we can't use title. We need opening sentence that echoes title and introduces. Something like: "想要一次性把大型网页建设做好，必须把握从规划到上线的每一个关键环节。" That's about 30-40 characters? Let's write longer: "想要一次性把大型网页建设做好，必须把握从规划到上线的每一个关键环节，下面我们就一步步拆解这套完整流程。" That's about 50 characters? Actually Chinese characters count: "想要一次性把大型网页建设做好，必须把握从规划到上线的每一个关键环节，下面我们就一步步拆解这套完整流程。" That's around 45 characters? Let's count: 想(1)要2一次3性4把5大6型7网8页9建10设11做12好13，14必须15把16握17从18规19划20到21上22线23的24每25一26个27关28键29环30节，31下32面33我34们35就36一37步38步39拆40解41这42套43完44整45流46程47。 So 47 characters. Need 150-250 characters per paragraph. So we need to expand.

Paragraph 1 should be 150-250 characters. So we need to write about 180 characters.

Let's craft paragraph 1 of approx 180 characters: talk about why large site construction matters, the need for systematic approach, and introduce that we will cover planning, design, development, launch.

Write: "大型网页建设听起来是件技术壮阔的事，但如果没有清晰的路线图，光靠热情是撑不住的。我们今天要聊的，正是从需求调研到上线运营这套完整流程的关键要点，帮助你把每一步都走得扎实、顺畅，避免踩坑。" Count characters: let's approximate. It's likely around 100? Need more. Let's count roughly: 大(1)型2网3页4建5设6听7起8是9事10件11技12术13壮14阔15的16事17，18但19若20果21没22有23清24晰25的26路27线28图29，30光31靠32热33情34是35撑36不37住38的39。这40段41话42的，43究44竟45是46从47需48求49调50研51到52上53线54运55营56这57套58完59整60流61程62的63关64键65要66点，67帮68助69你70把71每72一73步74都75走76得77扎78实、79顺80畅，81避82免83踩84坑85。 That's about 85 characters. Need 150-250. So expand more.

Add more: talk about typical pain points, importance of planning, etc.

Let's rewrite paragraph 1 with about 180 characters.

"大型网页建设听起来是技术壮阔的事，但如果没有清晰的路线图，光靠热情是撑不住的。我们今天要聊的，正是从需求调研到上线运营这套完整流程的关键要点，帮助你把每一步都走得扎实、顺畅，避免踩坑。先从整体目标说起，明确受众需求和业务目标，才能在后面的设计和开发中有的放矢。" Count characters approximate: Let's count quickly.

Still need 150-250. Add more sentences.

Add: "只有把这些基础问题弄清楚，后面的每个环节才不会出现返工或功能缺失的尴尬。接下来，我们会逐步展开规划、设计、开发、测试以及上线的关键细节。" Let's count added characters.

Paragraph 1 is ~183 characters, within 150-250. Good.

Paragraph 2: Planning stage details. Need 150-250 characters.
