用一句话说出一个生命过程，Claude 会画出做这件事的标本。Name a living process in one line, and Claude draws the specimen that does it.
Anatomy 的信条是 “物体本身就是解释”——不画方框、箭头和浮动标签，而是发明一台真实的机器，让它的运动本身就是概念。它画的是机器：锁、绘图仪、抽屉柜。
Anatomy Vita 把这条信条推进到生命。分子本来就是机器，照原样画；细胞、组织、器官则改用标本、教学模型和记录仪器的语言来画。为此它在 Anatomy 之上加了一层 bio 层，并立了七条新法则。kit 本身一行未改。
Anatomy's creed is “the object is the explanation” — no boxes, arrows or floating labels; invent a real machine whose motion is the concept. It draws machines: locks, plotters, chests of drawers.
Anatomy Vita carries that creed into life. Molecules really are machines, so they are drawn as such; cells, tissues and organs are drawn in the language of specimens, teaching models and recording instruments. To do that it adds a bio layer on top of Anatomy and seven new laws. The kit itself is untouched.
Vita 新增了什么What Vita adds
01扩充Extensions
- 题材：从机械到生命。原 Anatomy 画的是机器。Vita 把同一条信条推进到分子 → 细胞 → 组织 → 器官 → 系统 → 星球，规划 22 张图，已上线 8 张。Subject: from machines to life. Anatomy draws machines. Vita carries the same creed through molecule → cell → tissue → organ → system → planet: 22 figures planned, 8 live.
- bio 层，kit 零修改。所有扩展都在
bio/bio.mjs；kit/与scripts/原样复用，随时可以和上游同步。A bio layer, kit untouched. Every extension lives inbio/bio.mjs;kit/andscripts/are reused verbatim, so upstream can be merged at any time. - 染色系统。13 种真实染料 / 荧光蛋白（DAPI、GFP、RFP、伊红、苏木精、ATP、髓鞘、氧合/脱氧血、Na⁺、K⁺、tRNA、胞质）。
color-mix把四朝向色调推向染料色，明暗保留，图例色块直接引用染料名。A stain system. 13 real dyes and fluorescent proteins (DAPI, GFP, RFP, eosin, haematoxylin, ATP, myelin, oxy/deoxy blood, Na⁺, K⁺, tRNA, cytosol).color-mixpushes the four facing tones toward the dye, keeping the shading; legend swatches name the dye directly. - 看得进去的膜。
shellOf：前后两半的半透明膜壳，先画后半、再画内容、最后画前半，加高光——原 kit 只有不透明实心体。Membranes you can see into.shellOf: a translucent shell in two halves — back half, contents, front half with a gleam. The original kit only has opaque solids. - 标本语法。
plinth/standRod：带校准刻度尺、铭牌、螺丝的底座与支架杆。细胞以上的对象像实验室里那样放在玻片、支架、教学模型上，而不是硬套机器隐喻。Specimen grammar.plinth/standRod: bases with a calibrated scale, name plate and screws, plus stand rods. Above the cell, things sit on slides, stands and teaching-model bases as they would in a lab, instead of being forced into a machine metaphor. - 种子化变异。
rng(seed)：没有两个细胞一样，但每次构建都一样——生物的不规则性与可复现的构建同时成立。Seeded variation.rng(seed): no two cells alike, yet every build identical — biological irregularity and reproducible output at once. - 几何在浏览器里活着。
liveScript()把 iso-kit / lathe / tube 内联为页面里的 K / G / T，几何可逐帧重建，于是能表达生长、形变和拓扑变化（一个细胞的截面并集轮廓变成两个）。Geometry alive in the browser.liveScript()inlines iso-kit / lathe / tube as K / G / T inside the page, so geometry can be rebuilt every frame — growth, deformation, even topology change (one cell's cross-section union becoming two). - 深度收集器。
scene(P)：粒子、管段、零件带深度放进来，svg()一次从后往前画，让成百个离子和管段正确遮挡。A depth collector.scene(P): particles, tube pieces and parts go in with their depth;svg()paints back to front once, so hundreds of ions and tube segments occlude correctly. - 七条生命法则。标尺即真相、染色代替配色、时间承认被改写、粒子守恒、拓扑可以变、标本而非卡通、隐喻需要声明——在原绘图语法之上新增的生命专用规则。Seven laws of life. Scale is truth, stains not palettes, admit the time warp, conserve particles, let topology change, specimens not cartoons, declare metaphors — rules for living things on top of the original drawing grammar.
改进Improvements
- 统一运行时。
vitaLoop()：每张图同样的离屏暂停、闲置巡演、指针 / 点击 / 键盘、减少动态时静止，不再每张图各写一遍循环。One shared runtime.vitaLoop(): every figure pauses offscreen, tours when idle, answers pointer / click / keys and stands still under reduced motion the same way — no per-figure loop code. - 时间缩放写在读数里。µs 到小时的过程都在读数里标明“放慢 N×”或“加速 N×”，不再假装是实时。Time scaling in the readout. Processes from µs to hours state “slowed N×” or “sped up N×” in the readout instead of pretending to be real time.
- 守恒可验证。钠钾泵里 Na⁺、K⁺ 各 25 个，泵、漏、阻断全程守恒；乌本苷阻断后梯度消散已用 Playwright 驱动验证（Na⁺in 2→12、K⁺in 20→13）。Conservation you can check. The pump keeps 25 Na⁺ and 25 K⁺ through pumping, leaking and blocking; the gradient collapse after ouabain was verified by driving the page with Playwright (Na⁺in 2→12, K⁺in 20→13).
- 真实数据驱动。核糖体读的是真实 GFP 基因（238 aa + UAA）；驱动蛋白按 v(F) = 800·(1−(F/6.2)^1.4) nm/s；钠钾泵走 Post–Albers 六态；线粒体按 state 3 / state 4 耗氧比。Driven by real data. The ribosome reads the real GFP gene (238 aa + UAA); kinesin follows v(F) = 800·(1−(F/6.2)^1.4) nm/s; the pump steps through the six Post–Albers states; the mitochondrion uses measured state 3 / state 4 ratios.
- 事实栏。每页卡片下有一行真实数值（尺寸、速率、电位、能耗），与图中读数出自同一模型。A facts strip. Every page ends with a row of true numbers (size, rate, potential, energy cost) from the same model that drives the readout.
- 可嵌入的长文站点。
vitaPage()页面外壳 +?embed/#embed嵌入模式：同一页面既能全屏打开，也能嵌进首页长文；首页带尺度标尺、路线表和工具层说明。An essay site with embeds.vitaPage()shell plus?embed/#embed: each page opens full screen or sits inside the essay; the home page adds a scale ruler, roadmap and toolkit notes. - 双语（v3）。站点外壳、首页长文、各页副标题与事实栏都有中英两版；默认英文，中文浏览器自动显示中文；导航里可切换，记住选择，嵌入的图同步切换；也可用
?lang=en/?lang=zh直接指定。Bilingual (v3). Shell, essay, page subtitles and facts strips exist in English and Chinese; English by default, Chinese for Chinese-language browsers; switch in the nav, the choice is remembered and embedded figures follow;?lang=en/?lang=zhpick one directly. - 一键部署（v3）。
wrangler deploy把site/作为静态资源发布到 Cloudflare Workers。One-command deploy (v3).wrangler deploypublishessite/as static assets on Cloudflare Workers.
生命法则Laws of life
02每条法则都由 bio 层里一个具体的调用来执行，所以它不是口号，是代码。下图是这层关系的 UML 类图：bio 层继承 Anatomy，并实现七个「法则」接口。
Each law is enforced by a specific call in the bio layer, so it is code, not a slogan. The UML class diagram below shows the relationship: the bio layer extends Anatomy and realizes seven «law» interfaces.
- 标尺即真相。每张图的底座上都有一把校准过的刻度尺，标出真实尺寸。
plinth({ scale })Scale is truth. Every base carries a calibrated ruler marked in real units.plinth({ scale }) - 染色代替配色。颜色只来自真实的染料或荧光蛋白：DNA 是 DAPI 蓝，神经元是 GFP 绿，质子是 RFP 红。
stain(name, svg)Stains, not palettes. Colour comes only from real dyes or fluorescent proteins: DNA is DAPI blue, neurons GFP green, protons RFP red.stain(name, svg) - 承认时间被改写。动作电位以 µs 计、细胞分裂以小时计；读数永远写明“放慢 2000×”。
vitaSay("slowed N×")Admit the time warp. Action potentials take µs, cell division takes hours; the readout always says “slowed 2000×”.vitaSay("slowed N×") - 粒子守恒。质子、离子、dNTP 做布朗运动，但数量可数且守恒。
scene(P).put(ion)Conserve particles. Protons, ions and dNTPs jiggle, but they are countable and conserved.scene(P).put(ion) - 拓扑可以变。一个细胞真的变成两个：膜轮廓是截面并集，而非两个圆叠在一起。
liveScript() · unionTopology may change. One cell really becomes two: the membrane is a union of cross-sections, not two overlapping circles.liveScript() · union - 标本，而非卡通。细胞以上的对象放在玻片、盖玻片、支架或教学模型底座上，像实验室里真实摆放的那样。
plinth · standRod · shellOfSpecimens, not cartoons. Anything above a cell sits on a slide, coverslip, stand or teaching-model base, as it would in a lab.plinth · standRod · shellOf - 隐喻需要声明。只有无实体的过程（分化景观、反馈）才发明机器，并在图注里说明这是隐喻。
caption: "metaphor"Declare metaphors. Only processes with no body (fate landscapes, feedback) get an invented machine, and the caption says so.caption: "metaphor"
