Known limitations

• Every outline is straight-edged: bowls are octagonal by design, so there are no curves to refine; at very large sizes the chamfers read as geometry, not as drawn rounds.
• Slices and stencil gaps split glyphs into several contours (fontbakery contour_count warns and Speed trail contours differ from Black); below roughly 40 px the Black and Bold slits fill in, so use ss02 or Utility there.
• The italic is the only slope of the display cuts. The skeleton is drawn upright then leaned 13 degrees about y=300; the italic-specific forms are the single-storey a and g, the t and f crossbars, the plate-cut corners and the slice rows, not a second redraw of every letter.
• Speed trails run left of the advance (up to 420 units beyond it): containers that clip overflow will crop the first trails. Speed registers only with Black (Stencil, Regular, Bold have different advances).
• Speed is not a colour font (no COLR): two stacked text layers are needed. A few tiny residual nubs remain at the ends of some trails.
• ss01 plate figures differ from the default figures only modestly (tabular width, a footed 1, slightly heavier stems); they are not a separate race-number design.
• Stencil only opens glyphs that have counters; letters without islands (E F T L S ...) are unchanged from Black.
• ss02 does not exist in the Utility cuts (they have no slices) and ss03 there swaps the other way (Utility's default a is double-storey; ss03 gives the single-storey one).
• Kerning is measured from geometry and verified on sample pairs with HarfBuzz; there was no hand optical pass on accented capitals, ß, fractions or most punctuation. Letters, figures, special letters and 23 punctuation marks are kerned; accented letters follow their base.
• Not tuned for: Windows GDI aliased rendering (unhinted), Greek, Cyrillic, Vietnamese (no stacked marks), all-caps tracking tables (use case and add letter-spacing).
• fontbakery: universal and opentype profiles have 1 FAIL in each (opentype/STAT/ital_axis, missing-roman: the display family is italic-only by design) and the waived warnings listed in README.md.
