Light Left - find the star whose light left the year you were born

List the people for a card - a name and a birth month each - the card's date and roughly where you look up from. Free in the browser: each person's light-year birthday star, a naked-eye star whose light arriving now left it around their birth month, from 374 stars with Hipparcos parallaxes and their measured error bars; an honest tag for each match (on the year, near, stand-in, or still on its way for the very young); the evening month and how high it stands from your latitude; an all-sky atlas plate joining the stars into one constellation, a light ruler, and SVG, CSV, Markdown and JSON exports. One metered task writes the card's words - a title, a headline, a caption and a finding line per person, a footnote and a closing line - with one verdict by a fixed order: true light, mostly true or stand-ins; the page re-checks every reply. Nobody can buy or name a star. Built on @claude-office-skills/infographic; star data from Hipparcos (VizieR I/311) and the HYG database (CC BY-SA 4.0).
