/*
 * teddy_mm animation figures. Markup:
 *   <figure class="anim" data-anim="NAME">
 *     <div class="anim-stage" role="img" aria-label="ALT TEXT"></div>
 *     <figcaption>ONE SHORT CAPTION</figcaption>
 *   </figure>
 * data-aspect="4:3" | "1:1" | "21:9" | "3:2" | "2:1" | "4:5" on the figure or stage overrides 16:9.
 *
 * Colour tokens read by core.js (ctx.colors). They map onto the page's own variables, so they
 * follow the site's light and dark themes; override any --anim-* on a page or a single figure.
 * Lineage colours (nk, t, b, m) are new to the site: checked with the dataviz palette validator,
 * all four pairs, against #ffffff (light) and #1b1e22 (dark): CVD ΔE ≥ 8, normal-vision ΔE ≥ 15,
 * contrast ≥ 3:1. Myeloid sits close to TEDDY orange and NK close to ANM teal for deuteranopes,
 * so every lineage mark in a scene carries a direct text label.
