Shared section iconography.

`section_icon_name(title, href)` maps a navigation section (by its title/href
keywords) to a Phosphor icon name, or returns an empty string when no mapping
applies. This is the single source of truth so the docs catalog rail
(`partials/docs-nav.html` → `catalog_mark`) and the desktop navbar mega-dropdown
(`base.html` → `render_navbar_item`) stay visually consistent.

Callers decide the fallback (e.g. a numeric index) and the icon size:
    {% from 'partials/nav-icons.html' import section_icon_name %}
    {% let name = section_icon_name(title, href) | trim %}
    {% if name %}{{ icon(name, size=18) }}{% else %}{{ index }}{% end %}
#}
