/* Isaac R+ achievement guide.
   Scene: a phone propped next to the monitor at night, read between runs in a dim room.
   Palette: umber basement neutrals, bone text, tear-blue accent for interaction and progress;
   tier colours only for reward value. System fonts; the serif is for page and hub titles only.
   Type scale: 13 / 15 / 17 / 21 / 28-32 px, plus the h1.
   Shapes: containers (cards, panels) 14px, controls (chips, inputs, buttons) 10px,
   counters and tags fully round, inline source codes 4px (they sit in running text). */
