 * @brief Pinnacle experience presentation for the OJS Information For
 *        Authors / Readers / Librarians pages (information.tpl).
 *
 * Scope & ownership:
 *   - Every rule is scoped under `body.lm-layout-pinnacle .page_information`,
 *     so the certified Zenith presentation (zenith-information.css) and every
 *     other experience remain untouched.
 *   - Reuses the existing shared `.lm-info-*` classes emitted by
 *     information.tpl; Pinnacle markup is gated on
 *     `experience->id == 'pinnacle'` in the template.
 *
 * Palette / token conformance (CORRECTION PASS #3):
 *   - THIS FILE IS NOT A PALETTE SOURCE. It defines no color ramp and no
 *     custom `--lm-*` color variables.
 *   - Every color resolves from canonical Lumina tokens owned by
 *     PaletteEngine (`--lm-accent-*`, `--lm-primary`, `--lm-primary-rgb`,
 *     `--lm-link`, `--lm-surface-*`, `--lm-border`, `--lm-text-*`,
 *     `--lm-focus-ring`, `--lm-state-hover-tint`) or from the static
 *     foundation tokens (`--lm-shadow-*`, `--lm-radius-*`, `--lm-motion-*`).
 *     Zero hex/rgb/hsl literals appear below.
 *   - A journal runs a single active palette; all three audience pages share
 *     it. Audience identity is carried by the hero composition objects and the
 *     card glyphs, not by hue (no parallel palette system).
