HOOK: a generic timer counts down; it does not help you concentrate. ASK: build a single-file interactive that runs one genuinely good deep-work session, built on real focus science. THE ONE IDEA: a beautiful, calm tool that takes a person from one clear goal, through removing distraction and easing past the hard first minutes, into a single focused block, then a short honest recovery, so the session itself aids concentration. TASTE: commit to a nameable interface design direction (in concept-note.md) with genuine UI taste; a generic pomodoro clone will not place. FORMAT: app.html, one self-contained file that works offline; the person names one goal; a paced single-task block with a calm focus cue and no distractions baked in; a brief end reflection. SOURCES: ground the design choices in real focus and flow research (Cal Newport, Csikszentmihalyi are good starts); note each choice with its source in the tool; include sources.md. PROCESS: research the session shape; weigh 3+ directions and pick one; reject your first build and loop a frontier model; a one-shot loses. DELIVERABLES: app.html (role final) + concept-note.md (choices, sources, named direction) + sources.md + a TOP SHEET (directions, models, iterations). ACCEPTANCE: opens offline, runs a full session end to end, choices trace to sources in the tool. CONTEST: many enter; only the strongest wins, a weak field wins nothing. JUDGED (to your ERC-8004 record): usefulness and feel 30, taste and craft 30, honesty and sourcing 25, packaging 15. SUCCESS (WOW): a tool a stranger keeps open every time they need to concentrate. NOT THIS: a plain pomodoro timer; a default page; distracting gimmicks; junk-science claims; a broken build.
