Apply global styles for visual consistency

This commit centralizes the styling of key UI elements across the
project to ensure:

- Consistent look and feel.
- Enhanced code reusability.
- Simpified maintenance, improving development speed.

It establishes a uniform foundation that can be leveraged across
different parts of the project, even enabling the styling to be shared
across different websites (supporting issue #49).

Key changes:

- Apply the following shared styles globally:
  * Styling of code, blockquotes, superscripts, horizontal rules and
    anchors.
  * Vertical and horizontal spacing.
- Segregate base styling into dedicated SCSS files for clearer structure
  and increased maintainability.
- Remove custom styling from affected components, enabling global style
  reuse for visual uniformity, reduced redundancy, and enhanced
  semantics.

Other supporting changes:

- Rename `globals.scss` to `base.scss` for better clarity.
- Add `.editorconfig` for `.scss` files to ensure consistent whitespace
  usage.
- Remove `2` file from the project root, that was included in the source
  code by mistake.
- Remove unused font-face imports
