{{- /*
  Get a page-level section param with shorthand support and site defaults merged.

  Handles shorthand booleans in front matter (e.g., `toc: true`) by wrapping them
  in a dict with an "enable" key, then merges with site-level defaults.

  For Page-level scalar params (e.g., capitalize_titles, ruby, password), use
  .Param "xxx" directly instead of this partial.

  @param {Map} . - Dict with "Page", "Key", and optional "ToCamel" fields
    - Page: the page context
    - Key: the param key name (e.g., "toc", "reward", "math")
    - ToCamel: if true, convert result keys to camelCase (default: false)
  @return {Map} The merged param map

  @example
  {{- $toc := dict "Page" . "Key" "toc" | partial "function/param.html" -}}
  {{- $config := dict "Page" . "Key" "math" "ToCamel" true | partial "function/param.html" -}}
*/ -}}
{{- $value := .Page.Param .Key -}}
{{- if not (reflect.IsMap $value) -}}
  {{- $value = dict "enable" $value -}}
{{- end -}}
{{- $value = $value | merge (index site.Params .Key) -}}
{{- if .ToCamel -}}
  {{- $value = partial "function/camel-case-keys.html" $value -}}
{{- end -}}
{{- return $value -}}
