 * EVNav TH — self-hosted brand typefaces
 * IBM Plex Sans (Latin) + IBM Plex Sans Thai (Thai), weights 400 & 600.
 * License: SIL Open Font License 1.1 — see OFL-IBM-Plex.txt in this folder.
 * Source: @ibm/plex-sans 1.1.0 and @ibm/plex-sans-thai (npm, official IBM packages).
 *
 * Use the combined family:   font-family: var(--font-sans);
 * "EVNav Sans" picks the Latin file for Latin text and the Thai file for Thai
 * text via unicode-range, so a Thai-only page never downloads the Latin file
 * and vice versa.
