Side length per format: team table with songs a side; palette control

Side length "at most" per format is now the table the team supplied
(October 2026, from recordplayerexpert.com, songs counted at an average
4:32): 12" 22 / 15 min, 10" 15 / 12 min, 7" 7 / 5 min at 33 1/3 / 45 rpm.
Changes against the earlier microcut.studio figures: 10" 33 1/3 16 -> 15,
10" 45 11 -> 12, 7" 45 6 -> 5. The comfortable column stays the lower end
of microcut.studio's ranges.

- artist-platform.md: table with a songs column, both sources, and the
  three formats where cutting rooms disagree (10" 45 is now more generous
  than microcut.studio and Diggers Factory) as re-check points for the
  cutting engineer
- artist-order.html: LIM and the side-length table (songs column, sources)
- make-a-record.html: LIM; format cards show the at-most time and about
  how many songs a side; step 2 hint adds the songs; the last control in
  each colour row is now a labelled "Palette" pill with a colour wheel,
  showing the chosen colour and "Your colour" when a custom colour is set
