v0.3.0: System audio build

Today the interface came to life with sound! This included:

• Implementing cues for focusing, clicking, sliding, and toggling elements.
• Adding a subtle electronic hum that corresponds with the film grain effect.
• Writing a short jingle that complements the logo animation.
• Supporting vertical displays.
• Dropping small Easter eggs.

Over the week I’ll be planning the first minigame, which I intend to complete in a 72-hour sprint. It will be the most traditionally arcade-like of the bunch before I venture into more experimental territory.

Enjoy!
