📝 Walkthrough

Walkthrough

The gauge now renders progress with dynamic SVG arc paths and animated painted progress. CSS uses rounded caps and dot-specific styling. Tests validate rendered progress, animation, normalization, and edge cases. Visual fixtures cover aligned gauges and slot content across sizes. Icon attribution records now list Lucide only.

Changes

Gauge rendering

Layer / File(s) Summary
Dynamic arc path rendering
projects/core/src/gauge/gauge.ts
Gauge geometry generates partial fill paths from normalized progress. Progress animation uses CSS duration and easing, with cleanup on disconnect and replacement animations on updates.
Rounded arc and thumb styling
projects/core/src/gauge/gauge.css
Gauge paths use rounded caps. Dash animation and start-dot styling were removed. End-dot sizing and entry animation apply to the dot thumb.
Rendering and visual validation
projects/core/src/gauge/gauge.test.ts, projects/core/src/gauge/gauge.test.visual.ts, projects/core/src/gauge/gauge.examples.ts
Tests measure rendered path lengths and cover animation, normalization, caps, dot alignment, thumb visibility, and fill states. Visual fixtures and the large gauge example were updated.

Icon attribution records

Layer / File(s) Summary
Attribution and license record updates
projects/core/NOTICE.md, projects/core/notice.json, projects/core/src/icon/icons/NOTICE.md, projects/site/src/docs/foundations/iconography.md
Attribution records remove three icon libraries and retain Lucide. The iconography documentation identifies Lucide as the foundation of the Elements icon set.

Estimated code review effort: 3 (Moderate) | ~20 minutes

In `@projects/core/src/gauge/gauge.ts`:
- Around line 159-162: Update the GaugeElement lifecycle around
disconnectedCallback and `#stopProgressAnimation` so removing an actively
animating gauge does not preserve an intermediate `#paintedProgress`; either
settle it to `#targetProgress`() and schedule the necessary update on
disconnection, or restart the animation in connectedCallback. Add a regression
test covering removal and reinsertion without changing value or max, verifying
the gauge is fully updated.
