Teachers and L&D buyers are often shown a deck, a wireframe, or a promise of what a lesson might become. That does not answer the first question: what is the standard of finish? A lesson that only exists as slides still needs the teacher to assemble the period. Capability is claimed. It is not on the page.
Living Light is a Year 9–12 biology investigation into bioluminescence, finished as a public microsite. It is a literature synthesis with citations, wrapped in a site a class can actually use: research question, hypothesis, published Monterey Bay data, the chemistry of cold light, six case-study lanterns, a scored quiz, and a 45-minute run sheet. A teacher can run a period from it. A student can present from it. No login. No worksheet to print.
Live. Built by RETSA Group with Grok Build. Public at living-light.grok.me. A 45-minute period is already sequenced on the page. By the end, a class can explain cold light, name four jobs for a photon, and say what the 2017 Monterey Bay result does and does not prove.
Focused artefact, not an over-engineered platform. The point is the finish: longform, data, interaction and sources on one page, holding on a phone. Grok Build is how it was produced. Instructional design judgement is what it sequences, and what it refuses to fake.
