  Logo styling:
  - .logo is the visual style for the clickable text.
  - text-decoration: none removes the underline from the link.
  - display: inline-block makes the link behave like a small button-like element.
  - cursor: pointer shows that the item is clickable.

  Lightbox / click-to-enlarge styles

  Explanation for each block below (for beginners):

  1) .gallery img, .image-box img
     - Adds a `zoom-in` cursor to indicate the image is clickable.
     - Adds a small transform transition so hover feels smooth.

  2) .gallery img:hover, .image-box img:hover
     - Slightly scales the thumbnail on hover to give user feedback.

  3) .lightbox
     - Fullscreen fixed overlay that covers the entire viewport.
     - `display: none` keeps it hidden by default; adding `.open` will show it.
     - `background: rgba(0,0,0,0.85)` darkens the page so the image stands out.
     - `z-index: 2000` ensures it appears above other elements.

  4) .lightbox.open
     - When JavaScript adds the `open` class the overlay becomes a flex container
       and centers its contents both horizontally and vertically.

  5) .lightbox img
     - Restricts the enlarged image size with `max-width`/`max-height` so it never
       exceeds the viewport and remains fully visible on small screens.
     - Adds `cursor: zoom-out` to hint that clicking will close the lightbox.

  6) .lightbox .caption
     - Simple caption styling for alt text (white, centered).

  Notes about behavior:
  - The JavaScript toggles the `open` class and updates `aria-hidden`.
  - Clearing the image `src` on close releases memory in some browsers.
  - These styles are intentionally minimal so you can extend them (add close
    button, transitions, next/prev controls) once you're comfortable.
