v0.20.21

Changed

• Dashboard: eliminated double-render flicker — initial paint uses skeleton widgets and a stat-less greeting; real widgets replace skeletons in-place without resetting container.innerHTML
• Dashboard: weather widget now derives temperature unit symbol (°C / °F / K) from the units field returned by the weather API instead of always showing °C
• Dark mode: removed duplicate @media (prefers-color-scheme: dark) block from tokens.css; system-preference detection moved to a matchMedia listener in index.html for flash-free sync
• Tasks: view-toggle (list / Kanban) fades out at 40% opacity during re-render and fades back in, giving visible feedback of the switch

Fixed

• Tasks: inline style="width/height" on all Lucide icon instances replaced with utility CSS classes (icon-xs … icon-2xl, icon-11) defined in layout.css
• Tasks: edit-button inline size overrides removed; replaced with new .btn--icon-sm utility class
• Tasks: textarea resize: vertical and select min-height: 44px moved from inline styles to layout.css
• Dashboard: chipIcon inline style variable eliminated; chip icons now use class="icon-sm"
• Dashboard: settings, refresh, chevron, and other action icons converted from inline styles to CSS classes
• Weather API: server now forwards the configured units value in the response payload so the frontend can render the correct unit symbol
