Store the original form with diacritics (Cu Chulainn with accents, Lugh Lamhfada with the long mark) as one column and a simplified English form as another. The URL uses the simplified form for shareability. Both render on the page. List a few common variant spellings in an alternate_names array if they differ enough to matter for search.

Yes. Make the attestations array an array of objects with text (Book of Leinster, Lebor Gabala Erenn, Red Book of Hergest, etc), passage, and a short note. List mapping renders them as a structured citation list. For scholarly sites this turns each figure page into a navigable index of primary attestations.

Store equivalent_slugs as an array but include a confidence field per equivalent (well-attested, etymologically linked, conjectural). Selector mapping picks a different visual treatment based on confidence, so visitors see that Lugh-Lleu is a strong link while other proposed equivalences are more speculative. Honest framing beats casual conflation.

Yes. Each URL is added to the SleekRank sitemap. The base template is excluded and noindexed. Submit the sitemap in Search Console and new pages get crawled within hours of cache flush. Celtic-figure queries are under-competitive relative to Greek and Norse, so structured per-page pages can rank quickly.

Yes. Wikimedia Commons holds public-domain images of insular manuscripts (Book of Kells, Book of Leinster) and Gaulish inscriptional material (Pillar of the Boatmen, Coligny calendar). Store image URLs in the sheet and use selector mapping for hero images and og:image per page.

Cache duration is configurable per source. For active library development, set fifteen to sixty minutes; for stable references, a day or longer is fine. A manual flush via wp-cli makes urgent corrections appear immediately. The next request after flush rebuilds pages from the updated source.

Yes. Build a second page group for cycles and texts (Tain Bo Cuailnge, Mabinogion branches, Lebor Gabala). Each text page links to the figures who appear in it via slug arrays. Both groups read from coordinated sources, so the full corpus becomes a navigable linked structure.

No. The base template is a normal WordPress page. Style it however the rest of the site looks. The structured fields (original name, English form, tradition, attestations) render through your theme's typography and spacing. SleekRank only injects values into matched elements; the visual identity stays in the theme.
