Four SVG badges used as the bottom half of the composite scatter markers
on the Alternative Agents page: Claude Code, Codex CLI, Gemini CLI, and
OpenHands (shared by the OpenHands and "OpenHands Sub-agents" harnesses).

These are intentionally simple rounded-square badges in brand-adjacent
colors rather than hunted-down official CLI marks. The goal is just to
make two points for the same LLM run under different harnesses visually
distinct at a glance — e.g. claude-sonnet-4-5 under Claude Code vs
claude-sonnet-4-5 under OpenHands Sub-agents, which otherwise share the
exact same Anthropic company logo. Easy to swap for real logos later
without touching the scatter-plot code (just replace the SVG files).
