A finished portrait journal cover in the Nature/Science register: quiet, authoritative and scientifically honest. The background is a pure black void (#05070B) with fine speckled cryo-EM noise grain in the darkness. HERO: a single amyloid fibril rendered as a photoreal scientific molecular image. It rises vertically through the upper three-quarters of the cover, slightly off-axis and cropped by the top edge, and occupies the central band of the canvas, a little narrower than the full width and leaving wide black margins. Protein backbone is drawn as smooth glossy ribbons with flat beta-strand arrows. They are stacked as parallel layers along the fibril axis so the cross-beta stack reads layer by layer, like a sectioned column. Depth colouring runs from Ribbon Teal (#2B6F8F) in the near and upper layers to Amber Density (#E8A33D) in the accent fold and the warm core layers. A soft translucent isosurface shell surrounds the core. Shallow depth of field blurs the distant layers while the middle layers stay razor sharp. One cool key light comes from the upper left, with a faint rim light along the right edges of the ribbons. The molecule is the hero and takes the eye first. TYPE, all in Journal White (#EDEFF2), flat and untextured, in one neutral grotesque sans-serif: uniform medium stroke weight, no stroke contrast, blunt horizontal terminal cuts, closed apertures on C, S and a, slightly squared rounds, large x-height, tight optically corrected spacing. 1. Top edge: a tiny thin masthead strip with generous margin. At the left, small tracked-out text reading "{{journal_name}}". At the right, a tiny line reading "{{issue_date}}". Both are small, quiet and baseline-aligned, and they do not compete with the molecule. 2. Headline beneath the fibril, left-aligned on the left margin, spanning roughly two-thirds of the width: "CONFORMATIONAL POLYMORPHISM" in light-weight capitals, set on a single line, disciplined and small for a cover, not shouting. 3. Directly under it, sharing the same left edge and running a little narrower than the headline: "Cryo-EM structures of amyloid fibrils reveal distinct folds from a single sequence" in small regular-weight sentence case, set in two short lines with comfortable leading. The bottom of the cover keeps clear black air. Nothing else is written anywhere: no logos, no barcode, no extra captions.
