when i press backspace (to delete a task), akiflow runs into an error and needs to restart when this script is injected, can u figure out why that might be?
Assistant: Thanks for providing the script!

From what you described, the crash/restart happens **when pressing backspace to delete a task** while this script is injected. That suggests the script interacts with DOM nodes that might be removed or manipulated during the deletion, and some code might not handle those state changes gracefully.

Here are some likely reasons and points of failure in your script:

### 1. DOM Elements Might Become Null/Detached

If the user presses backspace to delete a task, the `.planner-task` element or its children might be removed from the DOM. Your code assumes the queried elements exist, but if they are removed during iteration or immediately afterward, operations on them might throw errors:

- In particular, these lines:
  ```js
  iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  ```
  - If `iconContainer.parentNode` is null or `durationHolder` is null, this will throw.

- Also:
  ```js
  const nestedTitleSpan = taskTitleSpan.querySelector('span');
  ```
  - `taskTitleSpan` could exist but `querySelector` could return null, so you guard here looks good.

- The overall issue is when the task card itself is deleted midway while your code runs or after your code modifies it.

### 2. Mutation / Event Timing Conflicts

Your function `fixStyling` is applying an effect on all `.planner-task` elements. If the deletion action triggers DOM mutations (removing `.planner-task`), and your code is attached to some events or reactively called, race conditions might cause invalid DOM references.

---

### How to troubleshoot / improve robustness

1. **Add null checks and fail-safes** at every point you access or manipulate elements that might be removed:

  For example, before:
  ```js
  iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  ```
  Ensure:
  ```js
  if (iconContainer && iconContainer.parentNode && durationHolder) {
    iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
  }
  ```

2. **Wrap risky DOM operations in try-catch** blocks to prevent uncaught exceptions from crashing the app:

  Example:
  ```js
  try {
    if (iconContainer && iconContainer.parentNode && durationHolder) {
      iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
    }
  } catch(e) {
    console.warn('Failed to move durationHolder:', e);
  }
  ```

3. **Avoid direct manipulation of the DOM on nodes that might be deleted soon**

   If deletion is triggered in the UI, you might want to debounce or delay this script execution, or better: listen to DOM mutation events or app-specific events and only update styles on existing nodes.

4. **Monitor errors in browser console**

   Replicate the crash and check the browser console for exact error messages and stack traces to pinpoint the faulty line.

### Additional detailed review of potential crash spots

- `iconContainer.parentNode.insertBefore(durationHolder, iconContainer);`  
  If either `iconContainer`, `iconContainer.parentNode`, or `durationHolder` is null or the node is already detached, this throws.

- In the event listener `handleColorSchemeChange`, the code calls:
  ```js
  document.querySelectorAll('.planner-task').forEach(applyDynamicStyles);
  ```
  If some `.planner-task` elements are partially removed, their internal elements might be missing.

- The `applyDynamicStyles` function accesses `taskCard.classList` and `taskCard.style` assuming `taskCard` is not null.

---

### Suggested minimal fixes to reduce the risk of errors:

Update `fixStyling` to include safe guards:

```js
const fixStyling = () => {
  const lightModeStyles = { /* ... */ };
  const darkModeStyles = { /* ... */ };
  const consistentStyles = { /* ... */ };

  function applyDynamicStyles(taskCard) {
    if (!taskCard) return; 
    const prefersDarkMode = window.matchMedia('(prefers-color-scheme: dark)').matches;
    const modeStyles = prefersDarkMode ? darkModeStyles : lightModeStyles;
    const fancyBorderClass = 'dailyGoal';
    const hasFancyBorder = taskCard.classList.contains(fancyBorderClass);

    for (const property in consistentStyles) {
      if (consistentStyles.hasOwnProperty(property)) {
        taskCard.style.setProperty(property, consistentStyles[property], 'important');
      }
    }

    if (!hasFancyBorder) {
      taskCard.style.setProperty('border', modeStyles.border, 'important');
      taskCard.style.setProperty('box-shadow', modeStyles['box-shadow'], 'important');
    } else {
      taskCard.style.removeProperty('border');
      taskCard.style.removeProperty('box-shadow');
    }
  }

  function handleColorSchemeChange(event) {
    document.querySelectorAll('.planner-task').forEach(applyDynamicStyles);
  }

  const taskCards = document.querySelectorAll('.planner-task');

  taskCards.forEach(taskCard => {
    if (!taskCard) return;

    try {
      taskCard.style.flexDirection = 'column';

      const iconContainer = taskCard.querySelector('.flex.items-center.justify-center.gap-px');
      if (iconContainer) {
        const durationHolder = iconContainer.querySelector('.h-5.relative.flex.items-center.justify-start.px-1.bg-grey-100.border.border-solid.border-white.hover\\:bg-grey-300.rounded-md.cursor-pointer');

        if (durationHolder && iconContainer.parentNode) {
          iconContainer.parentNode.insertBefore(durationHolder, iconContainer);
        }

        taskCard.appendChild(iconContainer);
        iconContainer.style.marginLeft = 'auto';
        iconContainer.style.paddingTop = '5px';
        iconContainer.style.marginRight = '0';
      }

      // Remove max height limitations
      taskCard.style.setProperty('max-height', 'none', 'important');
      taskCard.classList.remove('max-h-[54px]');

      // Improve layout of title span
      const taskTitleSpan = taskCard.querySelector('span.text-2xl.font-medium.text-grey-900.font-sans');
      if (taskTitleSpan) {
        taskTitleSpan.style.display = 'flex';

        const nestedTitleSpan = taskTitleSpan.querySelector('span');
        if (nestedTitleSpan) {
          nestedTitleSpan.style.wordBreak = 'normal';
          nestedTitleSpan.style.overflowWrap = 'break-word';
          nestedTitleSpan.style.whiteSpace = 'normal';
        }
      }

      // Remove h-5 from task header
      const taskHeader = taskCard.querySelector('.planner-task-header');
      if (taskHeader) {
        taskHeader.classList.remove('h-5');
      }

      // Remove h-5 from icons in icon container
      if (iconContainer) {
        const iconElementsWithH5 = iconContainer.querySelectorAll('.h-5');
        iconElementsWithH5.forEach(iconElement => {
          iconElement.classList.remove('h-5');
        });
      }

      // Apply mode-based styling
      applyDynamicStyles(taskCard);

    } catch (e) {
      console.warn('Error styling task card:', e);
    }
  });

  const colorSchemeMediaQuery = window.matchMedia('(prefers-color-scheme: dark)');
  colorSchemeMediaQuery.addEventListener('change', handleColorSchemeChange);
  window.addEventListener('beforeunload', () => {
    colorSchemeMediaQuery.removeEventListener('change', handleColorSchemeChange);
  });
};
```

### Summary

- Wrap DOM manipulation logic in `try-catch`.
- Always check if a node or its parent exists.
- Avoid assuming the node is attached — e.g., check `iconContainer && iconContainer.parentNode`.
- Add logging to locate exactly where it fails.
- Confirm what triggers the backspace event and interception; ensure this function isn't called at an invalid time on disconnected nodes.

If you apply these changes and the app still crashes, it would be helpful to get error details from your browser console.
