/* The public booking pages (/book/{token} and /booking/{token}). These wear the WEBSITE's look, not the hub's,
   because a client arrives from studiohummingbird.com and should see no seam: Playfair Display headings, Roboto
   body, Montserrat small caps, charcoal, gold, cream. Legibility as the portal: body 17px, line height 1.6 or
   more, text no lighter than #3e4b45 on white, every target 44px or more.
   The choosing step is Calendly's layout in the studio's colours, to the mock-up Victoria approved on 25 September
   (Main, Chosen and Phone boards): the studio on the left, the month in the middle, the chosen day's times on the
   right; stacked on a phone, the times under a rule below the month. No JavaScript anywhere: dates, month arrows
   and times are links, the form is a plain POST. */
