Morphing Text <mv-morphing-text>
相互融化的文字：两份叠放的副本交叉模糊，同时 SVG alpha 阈值滤镜把字形熔合成一团“黏稠”的液滴。

| 类型 | Web Component（<mv-morphing-text>） |
| 状态 | 稳定版 |
| Keywords | morph, gooey, blur, svg-filter, hero, rotating-text |
When to use
- A hero keyword should cycle through several words with a soft, gooey melt
- A centered standalone word loop is needed with no layout shift between words
Avoid when
- The changing word sits inline inside a sentence and its width should adapt → use Word Rotate instead
- A typed, letter-by-letter feel with a caret fits the tone better → use Typewriter instead
- Critical information appears in only one word of the loop; many readers will miss it

用法
标准标记，可在此基础上通过属性、data-* 和 CSS 变量进行定制：
<div style="display:grid;gap:1.25rem;justify-items:center;text-align:center">
<p style="margin:0;font-size:.8rem;letter-spacing:.14em;text-transform:uppercase;color:var(--mv-fg-muted)">Our process</p>
<h2 style="margin:0;font:800 clamp(2.6rem,8vw,5.2rem)/1 var(--mv-font-display);letter-spacing:-.045em">
<mv-morphing-text words="Imagine, Design, Prototype, Ship"></mv-morphing-text>
</h2>
<p style="margin:0;max-width:30rem;color:var(--mv-fg-muted);font-size:1.05rem;line-height:1.55">
Each step melts into the next: one continuous flow, from sketch to production.
</p>
<p style="margin:.5rem 0 0;font:700 clamp(1.4rem,3vw,2rem)/1.2 var(--mv-font-display);letter-spacing:-.03em">
Studios in <mv-morphing-text words="New York, London, Berlin, Tokyo" duration="900" pause="1400" style="color:var(--mv-accent);--mv-morphing-text-align:start"></mv-morphing-text>

Accessibility
A hidden copy reads the word list once; the animated part is aria-hidden. The box is sized to the longest word (no reflow). The loop is suspended off-screen and in hidden tabs; with reduced motion, the first word stays crisp and still. The filter is only active during the morph, so text at rest stays perfectly readable. Known limit: the cycle never ends on its own, and WCAG 2.2.2 asks for a way to stop motion that lasts more than 5 seconds next to other content: wire the paused attribute to a visible control (or stop it after a few cycles on mv-change) when the text sits in a reading area.
