/**
 * Checkbox toggle base — paint surface for the theme layer.
 *
 * Reads only canonical `--slds-c-checkboxtoggle-*` hooks. State paint
 * (`:hover`, `:focus-visible`, `:checked`, `:checked:hover`,
 * `:checked:focus`, `[disabled]`) is driven from the per-theme files
 * by reassigning canonical hooks under each pseudo-class selector
 * (out-of-carveout state pattern).
 *
 * Inner glyph geometry — the switch's circular knob (`::before`) and
 * the rotated checkmark stroke (`::after`) — stays as literal paint:
 * the positions and dimensions are proportional to the track size and
 * not customer-tunable as independent values.
