中文译文
我希望你扮演一名顶尖的基于物理的游戏玩法程序员。制作一个单文件（index.html）构建的建筑飞行躲避游戏。
游戏规格：
标题：Gravity Flux
核心机制：操控一个可自行膨胀的软体球体，穿越一个由不断闭合与扩张的有机几何缝隙构成的环境。
目标：保持高度，并在不接触的情况下穿过动态结构门。
技术要求：
单文件：合并 HTML、CSS 和原生 JavaScript，无任何依赖。
渲染：2D Canvas API。所有障碍物形状必须是程序化生成的数学曲线（贝塞尔路径），并使用正弦波随时间持续变形。
音频：利用 Web Audio API 合成环境脉冲音效，以及在穿过门时触发的反应式声学扫频。
设计风格：禅意抽象艺术风格。使用单色粉彩调色板，并配合深邃柔和的阴影（canvas 上的 shadowBlur），以强调空间深度与流体运动感。

I want you to act as a top-tier physics-based gameplay programmer. Produce a SINGLE FILE (index.html) build of an architectural flight evasion game.
GAME SPEC:
Title: Gravity Flux
Core mechanic: Navigate a self-inflating soft-body sphere through an environment of closing and expanding organic geometric gaps.
Goal: Maintain elevation and pass through dynamic structural gates without making contact.
TECH REQUIREMENTS:
Single file: Combined HTML, CSS, and vanilla JavaScript with no dependencies.
Rendering: 2D Canvas API. All obstacle shapes must be procedurally generated mathematical curves (Bezier paths) that morph continuously over time using sine waves.
Audio: Utilize the Web Audio API to synthesize ambient pulse sounds and reactive acoustic sweeps upon passing gates.
Design style: Zen-like abstract art style. Uses a monochromatic pastel palette with deep soft shadows (shadowBlur on canvas) to emphasize spatial depth and fluid motion.
