How much Poka reads

B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.

Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-fnt/src/main.rs (314 lines) and plugin.json. No unit tests or tests/samples.rs; the corpus has no .fnt sample. Covers .fnt. The card decodes the FNT header: version, size, face and device names, copyright, raster or vector kind, point size, resolution, pixel cell, widths, ascent, weight, style, charset, family and pitch, glyph range, default and break characters and the bits offset. Judgement: B4: the header is decoded in full, but no glyph is drawn.

What Poka does not read

Glyph bitmaps are not drawn
The character table (per-glyph widths and offsets) is not read
Vector fonts are named but their strokes are not decoded
Files over 16 MiB are cut (flagged)
