anime.js v4.5.0 does not read an element's CSS-cascaded `transform` value
when resolving an implicit "from" for decomposed transform sub-properties
(translateX/Y, scale, scaleX/Y, rotate) authored without an explicit
`[from, to]` array. It silently defaults to identity instead, so any
element relying on a stylesheet rule like
`.node { transform: translate(-50%, -50%) scale(0); }` to start hidden
renders at (or near) its final position/scale from the very first frame.
Confirmed via isolated puppeteer reproduction: this is baked into anime's
internal tween node (`_fromNumber`) at `.add()` time, independent of seek
order or priming.
Correct each affected tween's `_fromNumber`/`_number` with the true
CSS-cascaded value (decomposed via DOMMatrixReadOnly) before the instance's
first-ever seek, in the existing per-instance priming pass. Verified
against registry/blocks/flowchart and registry/examples/kinetic-type
(same "content resolves ahead of schedule" defect family from the U-final
adjudication) with real render+compare-item PSNR improvement.
