/* ==========================================================================
   AURALAR — foundations: tokens, reset, typography, shared controls.

   The house style is print. A household calendar is a thing you read across a
   kitchen at a glance, and the medium that has solved that problem for three
   hundred years is the printed page: a serif face, hairline rules doing the
   work that borders and shadows do on screen, and numerals set in a column so
   the eye can run down them.

   Two rules carried over from the previous version, both learned the hard way:

     * Cards are LIGHTER than the page, in BOTH themes. A sunken darker panel
       reads as a hole in the screen rather than a card on it.
     * Anything that changes once a second is tabular-figure and fixed-width. A
       clock that shifts the buttons beside it every second is worse than no
       clock at all.

   No web fonts anywhere. A wall panel that has just lost its wifi must still
   come up looking like itself, and Georgia has shipped on everything since
   1996.

/* --- Slate: the same page after dark --------------------------------------
   Not an inversion, and not the warm stock turned down. The first dark theme
   here tried to be the light one at night — a warm near-black with an olive
   cast — and warm colours at low luminance go muddy rather than cosy: the
   background read as dim rather than dark and the member colours sat in it
   without ever quite separating.

   This is cool instead, deliberately. Against a warm cream day theme, a cool
   night theme reads as a different time rather than a faded version of the
   same one, and every accent the app uses — the member dots, the ochre and
   blue of the charts, the red of a late job — gains separation against it
   instead of losing it.

   Not black, either. Pure black on a panel that is on all night is harsh, and
   it leaves nowhere to put a raised surface: a sheet lifting off the page has
   to be lighter than it, and #000 has no room underneath.

   Contrast, measured, not guessed (WCAG, against the darkest surface each is
   used on): ink 13.3:1, ink-2 7.2:1, ink-3 4.6:1 — the last one is the italic
   hint text, and it is the reason ink-3 is not darker than it looks like it
   wants to be.

   Other palettes were drawn and rejected: a warmer espresso, a neutral
   graphite, a bluer midnight, and a lifted pewter that was not really dark at
   all. Any of them is a five-line swap here if this one wears badly. */

                         nothing: the title keeps its full size and weight.
     inline            — in front of the name on the same line, lighter, with
                         a thin separator. Saves a line; costs a little
                         scanning speed when the list is long.
     tag               — a boxed chip. Loudest of the three, and the one that
