Title: Midnight Frequency
Exact creative prompt: Handcraft a standalone vintage radio interface with walnut brown casing, amber frequency display, concentric CSS speaker, tuning scale, rounded play switch, and volume slider. Use warm analog typography and subtle inset shadows. Play a soft synthesized sine drone only after explicit play, vary its pitch with the FM-style tuner, and support pause and volume. State this is synthesized audio, not a broadcast. All inline, offline, responsive.
Description: An intimate retro listening object that turns tuning a dial into a quiet synthetic sound experience.
Major visual techniques: Repeating radial speaker gradients; amber display glow; wood-tone panel; tactile control shadows.
Interaction model: Play or pause a local synthesized drone, tune pitch, and adjust volume.
