Easter Egg: Implement "Time Machine" (Raw HTML Mode)

[BarryS27]

Description

To demonstrate the importance of semantic HTML and the power of CSS, implement a "Time Machine" mode that strips away all styling, effectively taking the user back to the "early web" (circa 1991).

User Story

As a curious developer, I want to see the underlying HTML structure of the page without styles, so that I can verify the semantic quality of the markup.

Acceptance Criteria

• Trigger: The mode activates when the user adds ?time=1990 to the URL (e.g., https://barrys27.github.io/?time=1990).
• Effect:
  • Programmatically disable the main style.css stylesheet.
  • The page should render as black text on a white background with default browser fonts (Times New Roman).
  • (Optional) Show a browser alert() saying: "Welcome back to 1990. CSS hasn't been invented yet."
• Revert: Reloading the page without the parameter should restore the modern design.

Technical Implementation

Check window.location.search in script.js. If the parameter exists, find the <link> tag for the stylesheet and set .disabled = true.
