Constant Footer Size & Positioning

Ensure that the footer has a constant size across all pages and is always positioned at the bottom of the page, even when the content is shorter than the screen height.

Start by locating the footer component and its page-level styling, then compare its size and vertical position across pages with both short and long content. Done means the footer remains a consistent size and sits at the bottom when content is shorter than the viewport, without disrupting pages with longer content.
