Fix the duplicate page template across the whole site
Every URL we fetched (homepage, /residential, /commercial, all 9 commercial size pages, 12 industry pages, and every suburb page) returns the same 87-char title, the same 9-char meta description 'Melbourne', no H1, and roughly 13 words of body content. This is the single reason 31 ranked keywords are all stuck on page 3+. Generate unique title, meta, H1, and 500+ words per page from the URL slug. Suburb pages need '{Suburb} Solar Installation | Ezy Green Energy' style titles; commercial size pages need '{Size}kW Commercial Solar System Melbourne'.
