 * Bulletproof SVG sizing. The #aichat-root scoping plus min-/max-width
 * lockdown defeats common offenders:
 *   - themes that ship `img, svg { max-width: 100%; height: auto; }`
 *   - flex parents that calculate the cross-axis available size as 0
 *   - aggressive resets like `* { min-width: 0; }`
 *   - generic `svg { width: auto; }` from optimisers
