Add an obsolete_constellations companion sheet for the 30 or so historic constellations no longer recognized. The same template can render those pages with a status note explaining their absence from the modern IAU list. The 88-page corpus stays canonical; the obsolete pages add historical depth.

Each constellation row carries columns for Greek, Roman, and other-cultures mythology, with the other-cultures column structured as a JSON array of culture-and-story pairs. The template renders all of them with equal visual weight. Editorial review concentrates on filling the other-cultures column with credible cultural sources, not on choosing one tradition.

Yes. A static SVG sky map per constellation lives in the media library, referenced by an image_map_url column. A selector mapping renders the map; clicking individual stars in the SVG can link to per-star pages if the corpus also has a star library. The map and the mythology share one row.

The viewing months are based on when the constellation is highest in the sky at midnight for a mid-latitude observer. A small lookup table in the template adjusts for hemisphere. For more rigor, swap the column for ra_hours and let a small inline script compute the months from the right ascension.

Add a meteor_showers JSON array column with shower name and peak date. A list mapping renders the showers on the page. A reader on the Perseus page sees the Perseids; a reader on Leo sees the Leonids. The same data drives a separate meteor calendar page.

Yes. Add a deep_sky_objects JSON array column with Messier numbers and NGC names. A list mapping renders the list with anchors to a parallel deep-sky-object library (if you have one). One constellation page becomes the gateway to its sky's deep-sky catalog.

The IAU Working Group on Star Names publishes the canonical list of approved star names. When a star gets a formal name, the brightest_star column for the affected constellations updates, and the next cache refresh propagates the new name across the page and the JSON-LD. The corpus stays current without editor effort.

Yes. The hemisphere column drives a conditional mapping that frames the best-viewing-months block from the observer's perspective. Northern observers see the constellation high in their sky during one band of months; southern observers see different bands. The same row serves both audiences with a small conditional block.
