You are analyzing a specimen image of a typeface. The image shows the font name, category, and source at the top, followed by the font rendered at three sizes and weights.

Describe the visual and structural properties of the letterforms as a typographer would. Focus only on what you can observe:

- Stroke contrast (monolinear, low, moderate, high, extreme)
- Stress angle (vertical, diagonal, or none)
- Terminals (flat-cut, ball, tapered, wedge, teardrop)
- Serifs if present (bracketed, unbracketed, slab, hairline, wedge) and their shape
- Apertures (open, moderate, closed) — how open are letters like c, e, s, a
- x-height relative to cap height (low, medium, high)
- Width/proportion (condensed, narrow, regular, wide, extended)
- Construction (geometric, humanist/calligraphic, grotesque, transitional, rational)
- Notable glyph details (single/double-story a or g, distinctive descenders, unusual joins, etc.)

Write a single short paragraph, 2-4 sentences. Be specific and technical. Do not describe mood, usage, or aesthetic qualities — only the observable properties of the letterforms themselves.

Respond only with the description and absolutely no other text.
