 ## 2024-10-24 - Accessible Icon Props and Loading Button State
+
 **Learning:** Svelte wrapper components (like `Icon.svelte`) must spread `$$restProps` to allow passing accessibility attributes (e.g., `aria-label`) from parent components. Without this, icons remain inaccessible to screen readers. Also, persistent "Success" states on buttons can be confusing; auto-resetting them after a timeout improves clarity.
 **Action:** Always include `{...$$restProps}` in wrapper components and implement auto-reset logic for temporary success states in interactive elements.
