/* ============================================================================
   AP LIFE — design tokens + component primitives
   ============================================================================

   ONE token layer. Every colour, space, radius, duration and type step in the
   product resolves here. Nothing downstream should hard-code a hex value.

   DIRECTION: dark-first, layered graphite. Depth comes from SURFACE STEPS and
   hairline borders, not from shadows — a dark UI that leans on shadows just
   looks muddy. One accent (electric cobalt blue) carries "active / on-track /
   primary"
   and nothing else competes with it; amber and coral are semantic only. The
   greys are deliberately warm-neutral rather than blue-grey, because a blue-grey
   dark theme reads clinical and this product is personal.

   TYPE: one family (Archivo). The old UI used a serif display face for data,
   which made a performance dashboard read like a magazine. Hierarchy now comes
   from size, weight and tracking — which is also one fewer font to download on
   cellular.

   MIGRATION: the Tailwind CDN config in base.html maps its legacy colour names
   (paper-*, ink-*, surface-*, accent) onto these variables, so pages not yet
   rebuilt pick up the new palette automatically instead of staying light while
   the shell goes dark.

   adds weight skips any set where it is NULL — so this control is the input to
   progressive overload, not a nicety.

   The checked state uses `input:checked + .face`, deliberately NOT `:has()`.
   This is installed to an iPhone home screen; a sibling selector has worked
   since forever, while `:has()` has a Safari 15.4 floor and fails SILENTLY —
   the tap registers, the value posts, and the chip just never lights up, which
   reads as a broken control. (It did exactly that here first.) ------------- */
