/* whydot — marketing site and read-only console. Round 2.
 *
 * House brand: one dark ink on white, square corners, no colour palette
 * (hasna-brand-identity). Light mode only. Production serves Inter; this file
 * falls back to the system face for rendering.
 *
 * Round 2 is built on restraint: one typeface at two weights, a short type
 * scale, whitespace instead of boxes, hairlines only where a table needs them.
 * There are no cards, chips, washes or sidebars. The agent prompt is never
 * rendered; it lives in a <template> and reaches the clipboard through one
 * button, which is the only interactive control on any page.
 *
 * The single functional colour is the alarm red. It marks the two states that
 * end with a domain going dark (an expired registrant verification, clientHold)
 * and appears nowhere else.
