--- @module Mainpage/Directory
--- The grouped text directory at the foot of the page.
---
--- Text links and not tiles: image pills at this size cost about two screens on
--- a phone before any content appears, so anything that reintroduces artwork
--- here undoes the decision that retired them.
---
--- The band carries no card of its own, so its columns land on the same grid
--- lines as the cards above it. How many columns there are is not decided here
--- or anywhere else in Lua: `.home-dir` is `repeat(auto-fit, minmax(125px, 1fr))`,
--- so the groups reflow on their own and the module just emits all of them.

local nav = require('Module:Mainpage/Nav')

local p = {}

		-- join the article's outline and put six entries in the table of
		-- contents for what is a navigation block.
		box:tag('div')
			:addClass('home-dir__label')
			:attr('role', 'heading')
			:attr('aria-level', '2')
			:wikitext(group.label or '')

		-- A real list, because that is what a directory is: it gives a screen
		-- reader the count before the links and lets it be skipped in one move.
		-- The marker and indent are removed in CSS, not by flattening the list.
