- Around line 60-61: Update DeltaText and MetricTrend to derive tone, icon,
color, and accessible labels from the same rounded delta produced by
formatSignedDelta, rather than the raw value; preserve neutral styling and
announcements when rounding yields zero. Add coverage for positive and negative
values that round to zero at each supported display precision.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use the rounded delta for all directional UI state.
DeltaText and MetricTrend derive tone, icons, and labels from the raw value, while their formatters round it to zero. Suppressing only the sign leaves a zero value styled and announced as directional. Share the rounded numeric delta with tone, icon, color, and accessible-label logic, and test both signs at each display precision.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
