Fix clang-tidy misc-no-recursion, dead store bug, and improve site styling

Disable misc-no-recursion check — recursion is fundamental to trie
traversal and JSON parsing. Fix silent error in extract_entries() where
TP_ERR_JSON_DEPTH was set but never returned (dead store). Add custom
SCSS overrides to widen site content area and use consistent sans-serif
fonts.
