Cassette

Cassette employs a retro-futuristic, bold aesthetic centered on high-contrast black and yellow. Textures are a key visual element, with a CRT-like grain applied to background surfaces. Typography is compact and functional, balancing a monospaced font for details with a humanist sans-serif for impact. Components are lightweight with distinctive extreme corner rounding, contrasting with the sharp, graphic angles of the overall layout. Use Midnight Oil (#19181a) as the primary background for content areas. Apply a 900px border radius to all interactive elements like buttons and any card-like groupings. Utilize Cassette Yellow (#f0e226) for all primary calls to action, highlights, and functional icons. Set all body text and detailed information in Apercu Mono Pro at 13px or 14px, weight 400 for a consistent technical feel. Employ True Black (#000000) for primary text on light backgrounds and for high-contrast borders. Maintain an element gap of 8px for tight groupings and apply 13px for internal card padding. Use Paper White (#f5f4f0) for component backgrounds and badges that require a lighter surface. Avoid generic rectangular shapes; always use the extreme 900px border radius for interactive and contained elements. Do not introduce additional sans-serif fonts beyond Apercu Pro or mono fonts beyond Apercu Mono Pro. Never use Cassette Yellow (#f0e226) for non-interactive text or mere decoration; reserve its impact for active states and brand accents. Avoid soft, ambiguous color palettes; maintain the stark contrast between Midnight Oil/True Black and Cassette Yellow. Do not use subtle shadows for elevation; rely on strong color blocking and outline borders instead. Do not deviate from the grain texture on backgrounds; it's a signature visual element. Avoid decorative elements that feel 'modern' or 'clean'; embrace purposeful retro-futuristic graphics and sharp angles.
