The block-pixel wordmark — the brand identity, as the design system defines it.

opencode’s DESIGN.md is explicit that the identity is not a drawn logo: “the brand name rendered as a 5-row block of monospaced character cells, used in the primary nav and as the centerpiece of the hero TUI mockup”, and its icon rule is “small monospaced character glyphs, not bitmaps or SVG”. This script is the one source of that wordmark, so the landing page, the banner, the social card and the favicon cannot drift apart.

python3 tools/mk_wordmark.py ascii dormouse # the 5 rows of block cells python3 tools/mk_wordmark.py svg dormouse 8 # SVG rects, cell = 8 px

The SVG path emits RECTS, not : a block character’s advance width is a property of whatever monospace font the renderer happens to have, so a text-based wordmark would reflow differently in the browser, in the OG rasteriser and in a viewer. Rects are exact everywhere.
