text width={\qfdWhatW - 0.2}cm doesn't parse — the braces don't
evaluate the arithmetic, so TikZ sees "4.6 - 0.2cm" which isn't a
valid dimension. Pre-compute the narrower width with
\pgfmathsetmacro and reference the resulting macro instead.
Text box anchored at qfdLeftEdge + 0.1 with width qfdWhatW overflowed
0.1 cm past the cell's right edge into the Weight column, clipping
trailing words like "the", "lag,", "hob-". Shrink the box by 0.2 cm
so it has 0.1 cm clearance on both sides.
Each product now gets a profile line across all WHATs using the same
colour and dash pattern its legend entry already advertises, so the
shape of each competitor's strengths/weaknesses is readable at a glance
instead of having to mentally connect the dots.
Raise the header zone (qfdHdrH 3.2 → 4.2) so rotated HOW labels stop
crossing into the roof diamond grid, and wrap the perception title onto
two lines via text width so it stays inside its zone instead of bleeding
left over the H14/H15 column labels.
Drop the duplicated 13x15 strength matrix and 15x15 roof tables from
qfd.md; the same data already lives in quality-house.md's TikZ source.
qfd.md §3/§4 keep the narrative reading (priority list, conflict list)
and point to quality-house.md for the cells and basement sums. Both
files' regenerate/maintenance notes flipped to reflect the new contract.
Renders qfd.md §1-§4 as a classical House of Quality with 13 WHATs x 15
HOWs, roof correlations, and a perception zone scoring reMarkable 2,
Freewrite Traveler, and Pomera DM250 against the v0.1 target. Scores are
guessed, not measured; rationale and caveats are in the doc.
