Aesthetic inspiration: the hand-painted Technicolor look of a famous 1993 poppy-field music video (sky/box blue↔red shifts, hyper-real reds, warm blacks). Heartbox is original work and is not affiliated with any band, label, or rights holder.

3. Hand-tune app-specific ports only when the generator cannot express them.
4. Keep silver on cursor/border/punctuation tokens.
