/*
 * The knowledge base contents card.
 *
 * Built by parse-toc.js from the headings in the article, so this file styles
 * markup nothing in HubSpot authored. Everything is scoped under .parse-toc so
 * it cannot reach the article's own lists, and the colours are declared as
 * --parse-toc-* custom properties on the card itself rather than read from the
 * theme: the knowledge base theme does not publish brand variables, and a card
 * that inherits whatever the theme happens to define is a card that changes
 * colour the next time somebody edits the theme.
 *
 * Values are the Parse palette: Indigo #550088, Dark Indigo #25003B, Dark Lilac
 * #9966B8, Lilac #DFCEE8, Pink Steel #B6007C, Dark Gray #525252.
