/* 
Art Direction: 
Palette: OKLCH warm analog orange/yellow accent (vinyl), deep brown/black background (studio acoustics).
Rhythm: dark sections with occasional light inserts.
Typography: wide geometric sans for huge numbers (Impact-like character) + legible modern sans for body text.
Composition Idea: huge numbers for steps/lists (01, 02), cards with image overlap, radial light gradients.
