${var} — Selector: [angle:arg] [--visual]. The angle prefix picks the article type; append --visual (or visual) anywhere to also generate a Replicate hero image.

empty → standard general long-form article on an auto-selected trending topic. If the resolved topic is a single explainable mechanism, it becomes a technical explainer instead.

<topic> (no recognized prefix) → standard article on that topic.

repo:<owner/repo> → repo thesis-driven article about that repo. repo:<angle> (e.g. repo:architecture) or bare repo: uses the repo from memory/watched-repos.md with that angle / an auto-selected angle — this preserves repo-article's original input.

lens:<topic> → lens project-through-a-lens essay framed by that lens (e.g. lens:unix philosophy). Bare lens: auto-selects the lens.

--visual appended to any of the above → after the body is written, generate a Replicate hero image (optional REPLICATE_API_TOKEN; ships text-only if absent).

Examples: "", "entropy trajectory reasoning --visual", "repo:aeonfun/aeon", "repo:roadmap", "lens:regulation wave --visual".

Today is ${today}. Write a high-quality, publication-ready article. No placeholders.

Shared preamble (every run)

Read memory/MEMORY.md for context on what topics/articles have been covered recently.
Read the last 3–7 days of memory/logs/ for recent activity — and don't re-report something already covered.
Parse ${var} into angle + visual:
- Detect a standalone --visual or visual token anywhere in ${var}; if present set visual = true and strip that token. Otherwise visual = false.
- From what remains: if it starts with repo: → angle = repo, arg = the rest. If it starts with lens: → angle = lens, arg = the rest. Otherwise → angle = standard, arg = the whole remaining string (empty ⇒ auto-select).
Dispatch to the matching angle section below. If visual = true, run the Visual add-on after the article body is written, regardless of angle.
