Complete npm guide and migrate all guides to Sass @use modules

[Copilot]

The npm guide was incomplete (placeholder sections only) and all bundler guides were using the deprecated Sass @import syntax instead of the modern @use module system.

npm guide — completed

Filled in the stubbed-out Configure npm and Import Bootstrap sections:

• postcss.config.js with Autoprefixer
• index.html linking compiled CSS and Bootstrap's pre-built JS bundle from node_modules
• Full npm script set: css-compile, css-prefix, build, watch, serve, start, lint
• .stylelintrc.json extending stylelint-config-twbs-bootstrap
• Updated project structure tree to include postcss.config.js and .stylelintrc.json
• Fixed erroneous "Vite" reference in setup step 3

All bundler guides — @import → @use

Bootstrap v6 is fully @use/@forward-based and compiles without deprecation warnings when consumed via @use. Updated webpack, Parcel, and Vite guides accordingly:

// Before
@import "bootstrap/scss/bootstrap";

// After
@use "bootstrap/scss/bootstrap";

• webpack: removed silenceDeprecations from sass-loader options, updated css-loader comment, removed the deprecation warning note
• Parcel: removed the optional .sassrc.js silenceDeprecations block
• Vite: removed silenceDeprecations from vite.config.js css.preprocessorOptions, removed the deprecation warning note

The npm guide references two screenshots (npm-dev-server.png, npm-dev-server-bootstrap.png) that follow the same naming convention as other guides but don't exist yet as image assets.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/bootstrap/bootstrap/node_modules/.bin/astro build --root site (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Finish the npm guide in our Guides docs section. Be sure to use modern Sass modules instead of imports. Also be sure to include mention of all dependencies needed, including the postcss ones. Model the flow off our other, complete guides. Then, make sure the other guides are updated to the latest Sass modules approach.
