Bugfix:

- Update to @tabler/icons-svelte-runes for a more 'Svente 5' experience.

 - Adjust error handling in load functions, plain error thrown for handling in the error handler.

  - Fix the warning regarding a click handler attached to an <img> on the About page

  - Re-organise component directory

  - Remove unused font declarations from global.css

Features:
 - Add service-worker caching of FilterData API response to allow for filtering to work fully offline
