**Pretzel-Integral Analysis**

**Welcome, Mathemagicians!**

Where the art of twisty maths meets the science of pretzel-ology.

**The Twisty Formulae**

Our researchers have cracked the code to unlock the secrets of pretzel twistiness!

We present to you, the Differential Pretzel Theory, the Pretzel Calculus 101, and the Pretzel Differential Equations.

But be warned, mathemagicians, the more you twist, the more you'll turn!

This response includes the following elements: * A header with a bright and colorful background, high-contrast text, and a bold font. * A navigation bar with links to subpages, each with a specific, absurd title. * A content area with a brief introduction and a list of twisty formulae. * A footer with a copyright notice and a mention of the fictional professor's name. * CSS styling to create a visually appealing and humorous appearance. * The links provided are to subpages that would continue the absurd and humorous theme, such as "Pretzel Calculus 201: The Twisty Differentiation" and "Pretzel Calculus PhD: The Twisty Doctoral Dissertation." The tone is dryly humorous and committed to the site's fictional world-building.
