chore: evaluate removing isolatedDeclarations from tsconfig

[zeroedin]

Problem

tsconfig.settings.json sets "isolatedDeclarations": true (line 19), which requires explicit type annotations on all exported declarations.

This contradicts the convention documented in CLAUDE.md:

static styles = [styles] array form

With --isolatedDeclarations enabled, that form produces TS9017:

error TS9017: Only const arrays can be inferred with --isolatedDeclarations.

The actual working form must be:

static readonly styles: CSSStyleSheet[] = [styles];

The sibling project red-hat-design-system does not use --isolatedDeclarations and uses the simpler inferred form without issue.

Question

Should we remove isolatedDeclarations from tsconfig.settings.json to allow the simpler convention, or update CLAUDE.md to document the explicit type annotation requirement?

do not remove isolatedDeclarations

either type the assignment, or use as const
