Add objective O6 and criterion SC8 to the Business Case: visible colours

Drawing the first painting from a photograph showed colours that pass the
white-shade rule (SC3) but are still faint on the white background. Add O6
(every dot clearly visible: drop palette colours whose contrast with white is
below 2.0) and SC8, plus the WCAG contrast standard, an In Scope item, a risk
row and the Problem Statement sentence. SC3 is unchanged and still holds.

The limit of 2.0 was chosen by S01 from the measured palette of the reference
image: 8 of its 30 colours fall below it and the next is at 2.56, so 22 remain.

Record the delta re-review as RC-007 (verdict Go, terms confirmed by S01).
