Fretwork

A dark, vivid 16:9 workshop-manual deck for secondary-school practicals, music and maker lessons, and hands-on technical training. Mahogany-night cards carry heavy uppercase cream headings, mono measurement tags and a bench rail; bright sunlit photographs of hands, instruments and tools sit in square cream keyline plates, and colour cutaways show hidden structure beside native numbered callouts. Sky-blue ledgers and charts, one clipped mango action plate per card, and pink marks only on a flagged fault.
