MAGNIFIC Future Innovators — V8 phase-safe long-phrase rebuild

Target: 04:15.000 at 48 kHz (12,240,000 samples), no global time stretch.
Source: recovered stereo copy of the approved V2 source timeline.

Inserted long phrases (original-source timeline):
1. 00:07.632 -> 00:46.032 (38.400 s / 16 bars)
2. 00:33.712 -> 01:16.912 (43.200 s / 18 bars)
3. 00:40.912 -> 01:28.912 (48.000 s / 20 bars)

Joins in the 04:15 output:
1. 00:46.284
2. 01:55.942
3. 02:51.444

Each join uses an 80.437 ms phase-aligned linear crossfade. The loop copy begins
one crossfade-width before the matched phrase start, so the two overlapping
windows represent the same musical phase. This replaces the V7 crossfade method,
which overlaid the phrase end with audio after the phrase start.

The last 12.011 ms is silence padding after the source's natural fade to reach the
exact target sample count.
