/**
 * Shared theme-mode icons (Sun / Moon / System).
 *
 * Several components render the same theme picker (PlanHeaderMenu, ThemeTab,
 * historically MobileMenu / ModeToggle). They used to inline these SVGs
 * independently, which meant any tweak to a glyph had to be hunted down
 * across files. Centralizing them here keeps the iconography consistent.
 *
 * Each icon takes an optional `className` so callers control sizing —
 * the dropdown segmented controls use w-3.5, the settings tab uses w-3.
