Papan Presentasi Konsep Desain Audio Retro

A clean retro-futurist presentation board on a muted periwinkle-blue background with a minimalist editorial layout, displaying four analog-inspired audio product concept visuals arranged horizontally. On the far left, a partially cropped reference photo of a vintage reel-to-reel tape deck and silver stereo receiver resting on a wooden shelf against a warm off-white wall, featuring two large white reels with dark green centers, brushed metal knobs, a blue-lit display, and pale mint and silver hardware. To the right, three tall rounded-corner poster cards are evenly spaced, each rendered on cream paper with dark forest-green typography, mint-green product styling, and soft studio shadows. First poster: a spherical retro speaker and radio on a pedestal base with a pale mint body, circular front face, small display, and two side knobs, centered beneath the bold uppercase headline "[SOUND, REIMAGINED.]". Second poster: a mint-green vintage oscilloscope device with a CRT screen displaying a waveform, silver knobs, switches, and a metal tilt stand, beneath the bold uppercase headline "[WAVEFORM]". Third poster: a compact mint-green portable cassette recorder boombox with a handle, front cassette window, tactile buttons, speaker grille, and silver knobs, beneath the bold uppercase headline "[ANALOG STILL HITS.]". Each poster includes delicate microtype, fictional brand marks, and Swiss-modern layout icons. A restrained palette of dusty blue, cream, sage mint, forest green, silver, black, and warm wood. Subtle horizontal guide lines across the background board, with small footer text reading "[MJ REFERENCE]" on the lower left and "[KREA // GPT 2]" on the lower right.
