fix(skill): move Deep Space saffron to upper-right, matching reference art

The 'Meet Five, our intergalactic Cloud Native Hero' illustration shows
Saffron gold in the upper-RIGHT corner with Steel Teal dominating the
left/upper-left — the opposite of what we had.

Deep Space composition now:
- Charcoal at upper-left, lower-left, lower-right corners (three dark anchors)
- Saffron + Banana halo in upper-RIGHT corner (distant warm star accent)
- Steel Teal sweeps the upper sky from center-left (dominant night-sky blue)
- Second Steel Teal layer mid-left for depth
- Large white clearing center-right where Five stands
