TTF: Vertical Metrics with a 250-Unit Line Gap

Ascender and descender identical to the agreeing fixture, with 250 units of external leading declared in both lineGap fields. Renderers differ on whether line gap belongs inside the line box, above it, or split: this is the file that shows which one yours does. Original typeface, free to use.

TTF: Vertical Writing Metrics (vhea and vmtx)

A horizontal Latin face that also carries vhea and vmtx, so vertical-layout code has something small and predictable to run against: every glyph advances 1000 units downward with a 250-unit top side bearing. For testing writing-mode support and metric-table selection without needing a CJK font. Original typeface, free to use.
