A record-sleeve method for product pages

Warm type wins

1

Lead with the heavy note

One fat headline carries the room before any smaller detail joins in.

2

Keep the sleeve dark

Deep chipboard brown lets burnt-orange type feel pressed into stock.

3

Let curves do the selling

Rounded bowls make pricing, proof, and signups feel generous instead of stiff.

4

Print texture, not polish

Grain, borders, and earth panels add warmth without turning corporate-clean.
