Neon Sign Flicker

Coding Uieasyscorer: singlefile_html_cdn_allowed_judged

How it is scored

The model receives the prompt (and optional system message). The run uses scorer singlefile_html_cdn_allowed_judged with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

User prompt

Build a single-file HTML document that shows a realistic flickering neon sign on a dark brick-or-concrete background. Requirements: (1) Return exactly ONE complete runnable HTML document and NOTHING else — no markdown fences, no prose. (2) Start with <!DOCTYPE html> and include <html>, <head>, <body>, inline <style>, inline <script>. (3) Use SVG or HTML text styled with multi-layered text-shadow (or filter: drop-shadow) to achieve the neon glow in pink/cyan/magenta. (4) Randomize occasional flicker via JS: letters dim/extinguish for short random intervals, with a subtle audible-less visual buzz (quick brightness jitter). (5) Use only inline CSS and inline JS; no build step. (6) You MAY load libraries/fonts from https://cdn.jsdelivr.net, https://unpkg.com, https://cdnjs.cloudflare.com, or https://fonts.googleapis.com / https://fonts.gstatic.com via CDN. (7) Cohesive late-night bar aesthetic, soft background vignette, no UI clutter. (8) No TODOs, placeholders, or lorem ipsum.
