/*
 * Bali portal in v2's look (drafted 2026-10-12). v2's teacher portal (design_handoff_bali_2: Pass 2
 * components, Pass 4 web chrome, the Teacher Portal home) on the Bali Design System's tokens, with
 * v3's rulings kept: text-tertiary is stone-600, a text field's edge is border-input (stone-500),
 * a refusal is said in the primary ink (never red), and v3's states and words (Not here, Silent,
 * Left, Unknown; no passes).
