基于 φ = 1.618 计算完美分割尺寸
黄金比例 (Golden Ratio)，又称黄金分割，是指一条线段被分为两部分，其中较大部分与整体之比等于较小部分与较大部分之比，其比值约为 1.618。这个比例在自然界、艺术、建筑和设计中广泛出现，被认为是最能引起视觉美感的比例。
示例：若短边 a = 100，则长边 b = 100 × 1.618 = 161.8，总长 a + b = 261.8。验证：261.8 / 161.8 ≈ 161.8 / 100 ≈ 1.618。
三分法是将画面九等分；黄金比例则是更精确的数学比例（1.618）。两者都可以用于构图，但黄金分割线通常更贴近视觉重心。
因为大量心理学实验表明，符合黄金比例的设计更容易让人眼感到舒适、和谐，因此成为设计中约定俗成的比例。
Calculate perfect proportions based on φ = 1.618
The golden ratio (φ ≈ 1.618) is a mathematical proportion found in nature, art, and design. It divides a line so that the whole to the longer part equals the longer part to the shorter part.
The rule of thirds divides a frame into nine equal parts; the golden ratio is more precise (1.618). Both are compositional aids, but φ often places the focal point closer to the natural visual center.
Researchers have found that shapes and layouts built around φ are perceived as more balanced and harmonious, likely because φ appears frequently in natural forms.
