Closes #774

index.css declared all three Material Symbols fonts (~1 MB together), and the package gave no way to load just one. This builds on the opt-in entries from @tedi-design-system/core 6.10.0 (TEDI-Design-System/core#146) and mirrors TEDI-Design-System/react#994.

  • New src/styles/index-without-icons.scss (core's index-without-icons + vertical-spacing + cdk). index.scss is unchanged, so index.css stays the same for existing consumers.
  • build compiles both stylesheets, rewrites font paths in both, and copies core's icons/{outlined,rounded,sharp,all}.css to dist/icons/. Those point at the existing fonts/ folder.
  • New exports in both package.json files: ./index-without-icons.css, ./icons/*.css.
  • @tedi-design-system/core is pinned to exactly 6.11.2 (root and published src/package.json) so token changes only arrive through a deliberate bump.

Single-style setup in angular.json:

"styles": [
  "node_modules/@tedi-design-system/angular/index-without-icons.css",
  "node_modules/@tedi-design-system/angular/icons/outlined.css"
]

Docs: an "Icon fonts" section at the end of Get started (single-style setup, file table, PWA note for ngsw-config.json and Workbox), plus the same recommendation on the Icon story and type input.

The core 6.9.0 → 6.11.2 diff was checked for token and mixin changes: the removed --loader-skeleton-height-* tokens, focus-element mixin and --global-outline-* variables are not used here, so no component changes were needed.

Testing

  • npm run build: index.css references all three icon fonts, index-without-icons.css none, each icons/<style>.css exactly one, and dist/package.json contains the new exports.
  • Icon unit tests pass.

Summary by CodeRabbit

  • New Features
    • Added an option to load core styles without icon fonts and pair it with a stylesheet for a specific icon style.
    • Added separate icon-style stylesheets to the package’s build outputs.
  • Documentation
    • Added guidance on choosing icon styles, matching icons with their fonts, browser and PWA font caching, and precaching.

Build and export index-without-icons.css plus core's
icons/{outlined,rounded,sharp,all}.css next to index.css, which still declares
all three Material Symbols styles. Pin @TEDI-Design-System/core to 6.11.2.
Document the single-style setup and the PWA precache note in Get started.

📝 Walkthrough

The package adds a stylesheet entry without Material Symbols fonts and exports per-style icon CSS. The build generates both stylesheet variants and copies icon CSS and fonts. The documentation describes selecting one icon style and managing font caching.

Changes: Single-style icon font support

Layer / File(s) Summary
No-icons stylesheet and package exports
src/styles/index-without-icons.scss, src/package.json, package.json
Adds a stylesheet entry without icon fonts and exports it alongside per-style icon CSS. The build generates both stylesheet outputs, rewrites their font paths, and copies fonts and core icon CSS into dist. Both package manifests pin @tedi-design-system/core to 6.11.2.
Single-style icon usage guidance
src/docs/get-started.mdx, src/tedi/components/base/icon/icon.component.ts, src/tedi/components/base/icon/icon.stories.ts
Documents loading one icon style with the no-icons stylesheet, describes fallback rendering and browser and PWA font caching, and updates the icon component and story guidance.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to ca388

Consumers using another compatible core version may receive a second copy. The package remains mergeable with owner awareness, but the published dependency range should be corrected.

Security architecture risk: 🔵 Low · up to 33615

The change is an opt-in extension to package-local stylesheets. Existing stylesheet access remains available, and icon rendering behavior is unchanged. No introduced security-boundary bypass was identified, but the newly packed assets and downstream caching behavior were not independently validated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated propagation surface is package assets and consuming applications' stylesheet and font loading. The inspected change adds no authority-bearing component behavior. External consumer hosting, cache policies, and application-specific exposure remain outside the available evidence.

Trust Boundaries and Controls

  • observed — The copied icon stylesheets contain fixed relative font URLs, including the all-styles entry. They introduce no external asset origin in the inspected CSS. The new export mappings resolve to package-relative CSS files.

Resilience and Maintainability Implications

  • observed — Standalone release invocation and the workflow's git pull between build and publication predate this PR. Artifact-to-release identity and stale-output handling are therefore existing release considerations, not demonstrated security regressions introduced by selectable icon styles.

Hardening Proposals

  • proposed — Validate the new stylesheet export targets and their relative font references in the packed package before publication, and associate that package with its immutable build revision. This would strengthen release-contract assurance; missing validation is not evidence of a PR-introduced vulnerability.

Explanation

The implementation covers the main coding objectives in #774: it adds index-without-icons.scss, per-style exports, build copying and path rewriting, package exports, and documentation. The reported build verifies the CSS and package outputs, and Icon unit tests pass. However, #774 requires @tedi-design-system/core ^6.11.2; both package.json and src/package.json use the exact version 6.11.2. The PR also provides no evidence that the required linter passes. Code review, Chromatic review, and semantic commit format are process criteria and do not affect this coding assessment.
