/* Kumii v3 — the form builder shell. Typeform's light aesthetic, light ONLY.
 *
 * NO HEX CODES. Every colour is a token from tokens.css, and builder.html hard-sets
 * data-theme="light" so the light block of the console tokens is the only one in play. There is
 * deliberately no dark mode here: Typeform's and Formflow's builders are light-only, the
 * likeness Rob asked for is mostly a light aesthetic, and the dark console identity stays with
 * v1's dashboard. The likeness comes from layout, surface, radius and spacing - NOT from new
 * hues: the chromatic palette of this chrome is still --dash-accent plus --dash-warn (validated,
 * DE 28.8 apart), with the primary action worn as near-black INK, which is monochrome and is
 * also Typeform's own move.
 *
 * THE CONTAINMENT RULE, unchanged from revision 1 and not taste: no brand hue and no band hue in
 * the chrome - --dash-warn sits DE 3.5 from --series-keune under deuteranopia and the Draft chip
 * wears it near the brand switch, so the words Keune and miiki carry the identity. The ONE
 * exception is .frame, the centre card: it shows what the CUSTOMER sees, wears the brand fully,
 * and is boxed and captioned so the boundary between internal tool and customer surface stays
 * visible.
