/*
 * telpa docs visual system — direction A from the brand pdf with light + dark mode support.
 *
 * load order: bootstrap-reboot.min.css → brand-tokens.css → this file → page-specific css.
 * brand-tokens.css owns the raw palette (`--telpa-ink`, `--telpa-cream`, `--telpa-teal`) and the
 * semantic tokens (`--bg-page`, `--fg-strong`, etc.) that flip between light and dark mode.
 * this file references the semantic tokens almost everywhere so every surface tracks the
 * active mode automatically.
