[DTM] SOFT-4083: filter shadow dimension fields through the dimension-value hook

[pauloiankoski]

Summary

• render_shadow() concatenated offsetX/offsetY/blur/spread directly into the CSS shorthand without routing them through the dimension-value filter other dimension fields already use — so a token alias string written into one of those four fields rendered literally instead of resolving to real CSS.
• Routes all four fields through filterDimensionValue, mirroring the pattern render_size/render_half_size already use on the same class (not render_border, which only delegates to getBorderStyle/formatBorderWidth — a different mechanism than initially assumed).
• Both the inset and non-inset branches are covered, with computeDefault closures keeping the no-listener output byte-identical to before.

Test plan

• New test proving the alias case: an alias string in any of the four dimension fields now resolves through the filter instead of rendering literally.
• Regression test confirming plain numeric values (including 0) still render unchanged.
• render_color/opacity logic untouched — scope is exactly the four dimension fields.
• Full existing test suite green (18/18).
• npm run build clean.

Summary by CodeRabbit

• Bug Fixes
  • Shadow styles now correctly apply configured dimension-value transformations to offsets, blur, and spread values.
  • Unfiltered numeric shadow values continue to render with px units.

📝 Walkthrough

Walkthrough

render_shadow now filters shadow dimensions before applying pixel-unit fallbacks. Tests cover filtered CSS variables, opacity-based colors, and unfiltered numeric values, including zero spread.

Changes

Shadow dimension filtering

Layer / File(s)	Summary
Render and validate shadow dimensions src/css/index.js, __tests__/output-filters.test.js	render_shadow filters offsets, blur, and spread before assembling inset and non-inset shadows. Tests verify filtered values and px units for numeric values.

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

Merge Risk: ⚪ Minimal · up to 91760

The change routes shadow dimension fields through the existing filtering behavior while preserving numeric output; no actionable merge-blocking risk remains after normal checks and review.

Add an inset shadow regression case.

This test only exercises the non-inset branch. Add a case with inset: true and assert the inset prefix plus the resolved dimension values. This preserves the stated coverage for both shadow forms.
