/* Planora: shared styles for the sign-in page and the app.

   The idea is the school day in an indigo-violet family: one hue range (indigo ~245 to
   violet ~265) carries the whole interface, so it reads as calm and focused, and the only
   colours outside that family are the two marks that mean something:
   highlighter yellow means "today / now", red pen means "overdue". Yellow is the complement of
   indigo, so "today" is always the highest-contrast mark on the page.
   Proportion is roughly 60/30/10: ~60% soft lavender ground and white sheets (or navy in dark),
   ~30% ink and the deep indigo rail, ~10% saturated indigo/violet for pressable things.
   Subjects are colour-coded like exercise-book covers, in a fixed, colour-blind-checked order.

   One typeface, Archivo, uses its width axis by job: expanded for page titles, normal for
   reading, condensed for times and numbers (the timetable voice).

   Everything is drawn like a stamped exercise book: 2px ink outlines and hard offset shadows,
   no blur and no glass. Buttons press down into their shadow. The focus timer and test
   countdown are split-flap tiles, like a station departure board. */

   One voice everywhere: things land like a stamp on paper. They drop a few pixels with a little

   (.view.enter), never when it re-renders after an edit, so typing and ticking stay still.
   Keyframes use the `translate` property so they never fight a component's own transform, and
   `backwards` fill so nothing keeps a transform (and a new containing block) after it lands.
