/* GoalSchema — page layer.
   Nocturne (assets/css/nocturne.css) owns every color, font, space, radius and
   shadow. Nothing here hard-codes a hex or a font: values are var(--…) or a
   layout number the token scale does not carry (breakpoints, max-widths).
   Direction, per the system guide: left-aligned and asymmetric, outlined
   actions, rules that fade to transparent at their ends, and exactly one
   full-bleed saturated band on the landing page. */
