+/*
+ * TAROT CARD watch face
+ *
+ * Draw from a deck of tarot cards. Can choose between major arcana only or
+ * entire deck.
+ *
+ * In tarot reading, a card orientation can be upright or inverted, and the
+ * interpertation of the card can change depending on this state. This face
+ * lights the alarm indicator to show when a card is inverted. Just ignore it
+ * if you prefer not to deal with card inversions.
+ *
+ * This face uses the terms "Wands", "Cups", "Swords" and "Coins" for the four
+ * suits, and numbers to represent the 14 ranked cards, with the cards 11-14
+ * representing the Page, the Knight, the Queen, and King respectively.
+ *
+ * Default draw is a 3-card major arcana spread.
+ *
+ * To make it easier to keep track of where you are in the list of drawn cards,
+ * after drawing, "St" is shown for the 1st card in the spread and "En" is
+ * shown for the last card.
+ *
+ * At any point, the mode button can be held to return to your first configured
+ * watch face.
+ *
+ * When "Major" or "All" is shown:
+ * - Light button: cycle # of cards to draw
+ * - Light button (long press): toggle between major arcana and all cards
+ * - Alarm button: shuffle deck and draw cards
+ *
+ * After cards are drawn/showing:
+ * - Light button: view the next drawn card
+ * - Alarm button: shuffle and re-draw new cards
+ * - Light button (long press): go back to Draw screen, for choosing different draw parameters.
