Note

Medium Risk
Upgrades the CSS build pipeline with a major css-loader jump (v3→v7) and related PostCSS ecosystem bumps, which can subtly change CSS Modules output and webpack build behavior despite being dev-time only.

Overview
Updates frontend build dependencies by bumping css-loader from ^3.1.0 to ^7.1.4 and postcss from 8.5.4 to 8.5.12.

package-lock.json is refreshed accordingly, pulling newer postcss-modules*/icss-utils versions and updating css-loader requirements/peer deps (now expects Node >=18.12.0 and newer webpack peer ranges).

css-loader v7 incompatible with style-loader v0.23

High Severity

Upgrading css-loader from v3 to v7 without upgrading style-loader (still at v0.23.1) breaks CSS in development mode. Starting with css-loader v4, the esModule option defaults to true, producing ES module output. style-loader v0.23.1 expects CommonJS output and cannot properly process the new format, causing styles to silently fail to apply. Production builds using MiniCssExtractPlugin.loader are unaffected. style-loader needs to be upgraded to at least v2+ for compatibility.
