docs: improve English clarity in documentation files

[Copilot]

Overview

This PR improves the English clarity and naturalness in 9 documentation files under website/docs/en/guide/. Many paragraphs were translated from Chinese and contained phrasing that didn't sound like authentic, professional English. All changes are minor wording improvements that make the text more idiomatic without altering the original meaning.

Motivation

The documentation contained several patterns that indicated direct translation:

• Awkward verb tenses ("switched" vs "has switched")
• Unnatural constructions ("focuses strongly" vs "places a strong focus")
• Non-idiomatic phrases ("give you an intuitive feel for" vs "give you an intuitive sense of")
• Inconsistent terminology (mixed capitalization of tool names)

These patterns made the documentation less accessible and professional, particularly for native English speakers.

Changes Made

Files Updated (9 total)

Getting Started:

• start/index.mdx - Introduction page
• start/quick-start.mdx - Quick start guide

Basic Guides:

• basic/server.mdx - Dev server documentation
• basic/html-template.mdx - HTML templates guide
• basic/static-assets.mdx - Static assets guide

Advanced Guides:

• advanced/env-vars.mdx - Environment variables guide
• advanced/hmr.mdx - Hot module replacement guide

Optimization & FAQ:

• optimization/build-performance.mdx - Build performance optimization
• faq/general.mdx - General FAQ

Key Improvements

More natural phrasing:

• "thoughtfully designed" → "carefully designed"
• "that fully unleashes" → "while fully leveraging"
• "pursues lightweight and flexibility" → "focuses on being lightweight and flexible"

Better consistency:

• Unified verb tenses for similar actions
• Consistent tool name capitalization (Prettier, ESLint, Biome)
• Standardized phrasing across sections

Technical accuracy:

• "invalid code" → "dead code" (proper compiler terminology)
• "during the build" → "during compilation" (more precise)
• "React Refresh" instead of "react-refresh" (proper case)

Clearer language:

• "optimization methods" → "optimization strategies"
• "which is a library development tool" → "a library development tool"
• "runs on localhost:5173" → "runs on http://localhost:5173"

Testing

• ✅ All changes pass Prettier formatting checks
• ✅ No breaking changes to code or functionality
• ✅ Preserved all technical terms and product names
• ✅ Maintained simple language suitable for non-native English readers

Notes

• Total changes: 26 lines modified across 9 files
• All changes preserve the original meaning
• No functional changes, only documentation improvements
• Follows project guidelines: max 10 files per PR, "docs:" prefix in title

Original prompt

Improve the English docs in website/docs/en. Many paragraphs were
translated from Chinese and may sound unnatural.

  Rewrite sentences that don't read like authentic, professional English —
  **without changing their meaning** — so they match the tone of
  high-quality open-source docs.


  - **IMPORTANT:** Only change a sentence if it clearly improves clarity or
  correctness.

  - **IMPORTANT:** Don't alter the original meaning.

  - If you edit files in `docs/en`, check the same files in `docs/zh` to see
  if similar updates are needed.

  - Use clear, simple language for non-native English readers.

  - Keep reasonable technical abbreviations (e.g., `dev server`).

  - Use sentence case for Markdown headings.

  - Don't change more than 10 files in one PR.

  - Start PR titles with `docs:`.
