/* Bioway — bioway.au
 *
 * BIO-03-33: this replaces the soil-profile theme. That design was deliberate
 * and well-made — the O/A/B/C/R horizons, the depth rail, depth.js — and it is
 * being discarded on the operator's instruction, not because it was broken. It
 * stays in git history.
 *
 * Direction now: green, fresh, organic, alive. Same system as the research site
 * at setup.bioway.au — the tokens below are the shared layer and are duplicated
 * there verbatim, so the two surfaces read as one brand.
 *
 * TYPE. Be Vietnam Pro leads the sans stack even though this page is currently
 * English-only. A stack that leads with a face lacking precomposed Vietnamese
 * glyphs breaks per-character — the base letter renders from one font and the
 * tone mark from another. This page will carry Vietnamese eventually; picking
 * the right stack now costs nothing and picking it later costs a retrofit.
