/* Amphion book page (book.amphionstudio.com). Grammar A, the Amphion "Wake-Up"
   storybook in its Atlantean blue paint: pill + circle geometry, soft tinted
   shadows, sub-1 degree tilts, the honey-gold moon for the action.
   External file on purpose: the desk serves this page under a strict CSP
   (style-src 'self'), so there is no inline style anywhere on the page.

   Theme: DARK is the default and lives on :root, so the page paints dark before
   any script runs. Light is the opt-in override (data-theme="light" on <html>,
   set by book.js from the viewer's saved pick). Every surface that carries text
   or a control is opaque: tints are color-mix of two solid colors, never of a
   color and transparent. Alpha is left only on shadows, the backdrop wash and
   the decorative rings, none of which sit under text. */
