/* LearnColorpuncture — the stylesheet.
 *
 * ⭐ THE INTENT: clear, calm, luminous, precise, grounded. A serious practitioner learning
 *    environment, not a wellness brochure and not Sacred Altar (which is deep violet, ornamented,
 *    and belongs to a different practice — nothing here borrows from it).
 *
 * ⚠️ COLOUR IS THE SUBJECT MATTER, so it is used as LIGHT: a warm near-white ground, deep
 *    ink text, and a narrow spectrum accent used sparingly for state — never a rainbow, and
 *    never carrying meaning that the words do not also carry (colour alone must not be the only
 *    signal for a locked state, which is why every tag has a word in it).
 *
 * Dark mode is honoured because people study at night.
