💡 What: Added unique keys to {#each} loops in src/components/Records.svelte (Object.keys(records) and unusedRecordsClasses).
🎯 Why: Prevents inefficient DOM updates and potential state corruption in RecordComponent when the list of records changes. Without keys, Svelte may reuse component instances incorrectly, leading to stale or incorrect internal state (e.g., edit mode or uninitialized values).
📊 Impact: Reduces unnecessary re-renders and ensures correct component lifecycle. While difficult to quantify in micro-benchmarks without user interaction, it eliminates a class of potential bugs and improves rendering efficiency for dynamic lists.
🔬 Measurement: Verified by manual code review and ensuring yarn vitest run passes. The change is a standard Svelte best practice for dynamic lists.

Note: Ran yarn format which updated formatting in several files to comply with project linting rules.

💡 What: Added unique keys to `{#each}` loops in `src/components/Records.svelte` (`Object.keys(records)` and `unusedRecordsClasses`).
🎯 Why: Prevents inefficient DOM updates and potential state corruption in `RecordComponent` when the list of records changes. Without keys, Svelte may reuse component instances incorrectly, leading to stale or incorrect internal state (e.g., `edit` mode or uninitialized values).
📊 Impact: Reduces unnecessary re-renders and ensures correct component lifecycle. While difficult to quantify in micro-benchmarks without user interaction, it eliminates a class of potential bugs and improves rendering efficiency for dynamic lists.
🔬 Measurement: Verified by manual code review and ensuring `yarn vitest run` passes. The change is a standard Svelte best practice for dynamic lists.

Note: Ran `yarn format` which updated formatting in several files to comply with project linting rules.
