Don't define body or global rules inside a component stylesheet
Global/body styling belongs in a shared global stylesheet, not scoped component files, to avoid leaking and surprising overrides.

Bad example
Old codescss
| 1 | // header.scss |
| 2 | :global { body { background: #eaeaea; } } |
Explanation (EN)
A component stylesheet can unexpectedly change unrelated page elements through a global selector.

Good example
New codescss
| 1 | // global.scss |
| 2 | body { background: #eaeaea; } |
| 3 | // header.scss styles only the header |

Notes (EN)
Place application-wide baseline styles in their owned global layer and scope component styles to the component's actual targets.
Exceptions / Tradeoffs (EN)
A modal may deliberately manage a body scroll-lock state through the framework's supported lifecycle. Moving a rule globally can change when it loads, so preserve that lifecycle.
