 * rindas 5-222, t.i. viss `<style>` bloks, kas sākas ar "Design tokens".
 *
 * NEREDIĢĒT PĒC IZSKATA. Lietotāja lēmums 2026-10-01: krāsas, fonti, atstarpes,
 * rādiusi, ēnas un komponentes ir 1:1, neko neizdomāt. Ja kaut kas šeit mainās,
 * tas vairs nav etalons, un `scripts/test_design_tokens.sh` to pamana.
 *
 * APZINĀTI NAV pārnests etalona 1. rindas `<style>` bloks. Tas ir claude.ai
 * artefakta ietvars, ne dizains: tajā ir cits fons (#faf9f5) un teksta krāsa
 * (#141413) nekā dizaina tokenos (#faf9f7 / #17181a), un dizaina bloks tos
 * tūlīt pārraksta ar var(--bg) / var(--ink). Tā `:root` iekšējās atkāpes ir
 * artefakta rāmim; mūsu lapās tās pievienotu atstarpi, kuras etalonā nav.
 * Drošās zonas (env(safe-area-inset-*)) dizaina bloks apstrādā pats --
 * topbar, fab, sheet un toast.
