/*
 * ternnotes.app — "Atelier" (8 Oct 2026; was "Desk")
 *
 * Paper on a limewashed desk under window light by day, walnut under a lamp
 * at night. Everything that matters is an object resting on it — cloth,
 * cotton paper, ink, glass — and the interface is glass laid over it.
 * The ink is warm near-black, never blue-grey. It is the same palette as the
 * app — someone arriving here and then opening Tern should not feel they have
 * gone somewhere else.
 *
 * Two rules run through all of it, both taken from the app:
 *   An edge is a hairline, never a rule.
 *   A shadow is ink, never black, and is two shadows — one tight enough to say
 *   the thing is resting on something, one wide enough to say how far off.
