/* lakes-hydro-lab — Sprint 2 — design v0.1
 *
 * Aesthetic: "Atmospheric scientific instrument".
 * Editorial broadsheet feel — Fraunces serif display + IBM Plex Sans body + Mono numerics.
 * Light parchment ground, deep flood-water teal accent, peat-amber for historical events.
 * Sharp 1px hairlines, no rounded cards, tabular numbers in mono.
 * Deliberately distinct from sister project LTV-5m's navy + gold palette.
