/*
 * ---------- Planner (My Day Planner 01 / A-hybrid mock flow) ----------
 * Own stylesheet rather than folding ~200 lines into components.css —
 * this is a whole application state (Home replacement), not a small
 * addition to an existing section. Reuses existing tokens throughout
 * (--accent, --detail, --line, --radius-control, --surface) — no new
 * global tokens introduced; the graphite/warm-light theme system and
 * citron-accent discipline established elsewhere are unchanged here.
 *
 * Exception, deliberate: Planner Top Zone / Astra Variant 2 "Soft
 * tiles" introduces the small set of --tile-, --nav-ghost-fill,
 * --nav-icon, --month-text custom properties below. The approved
 * reference gave exact hex values
 * for the week-strip's dark palette that don't coincide with any
 * existing token (Today's fill/text are the one exception — those
 * match var(--accent)/var(--ink) exactly and reuse them directly, no
 * new variable). These are declared once here, dark-default on bare
 * :root (mirroring tokens.css's own dark-is-the-default convention),
 * with a light-theme block that substitutes the existing light tokens
 * instead of inventing unreviewed light-mode hex values — the approved
 * reference is a dark-mode screenshot only.
