fix(logo): resolve word superposition and reduce animation cost

Browse Source 
The previous commit only masked the emoji row's crossing (via the
white flash timed to their fade). The text row ("love"/"envelope")
still animated opacity down while sitting fully centered on top of
each other, so the two words visibly superposed for a beat with no
flash to hide it there.

Fix applies the same technique to both rows: x and opacity now reach
their end state (centered / invisible) together, so there's no frame
where a glyph is both fully opaque and fully overlapping another.
Verified via a fresh screenshot mid-transition - no double-exposure.

Also addressed reported animation lag: dropped the rotate wobble
(one fewer animated property per element), cut keyframe count 8->7,
shortened 2.4s -> 1.8s, trimmed the flash's blur/spread, and added
willChange hints so all layers are promoted upfront rather than
mid-animation. Playwright rAF sampling over the full animation now
shows a flat 60fps with zero frames slower than 30fps.
