/* =====================================================================
   iq-tools.css: the IQ Books landing treatment for the free-tool pages
   (/invoice-template, /quote-template, /receipt-template, /vat-calculator,
   /self-employed-tax-calculator, /mtd-software).

   Part 1 is lifted from index.html (the IQ Books landing): tokens, type,
   masthead, drawer, buttons, section heads, FAQ, final CTA, colophon and
   the reveal system, so these pages read as IQ Books pages. Part 2 adds
   the components the tools need. Load with /iq-landing-polish.css + .js
   for the shared motion layer (it keys off --brand).
