// navDefs is appended to every theme template when parsing.
// It defines named sub-templates shared across all themes:
// - "splashGate" — synchronous script: first child of <body>; sets html.sno-splash-skip when
// splash should not run (?splash=0, not index.html, or Referer from same-site index/pageN).
// - "navhints" — keyboard shortcut hint bar HTML
// - "navmodal" — full-screen expanded-post modal HTML + image-sizing CSS
// - "navscript" — keyboard navigation + Web Audio; splash/nav/modal sounds from themeSoundsJSON (per theme)
//
// Each theme calls {{template "splashGate"}}, {{template "navhints" .}}, {{template "navmodal" .}},
// and {{template "navscript" .}} at the appropriate points in its HTML.
// All theme-specific CSS lives in each theme file so themes stay self-contained.
