     This is a DIFFERENT semantic than the confidence badges above:
     confidence colors mean "how much to trust this lap's detection,"
     these mean "gained/lost time vs. a reference lap," the same
     distinction documented in frontend/src/components/DeltaStripChart.jsx.
     No official FOM/F1 hex values are published anywhere public — these
     are reasonable, WCAG-mindful approximations of the broadcast
     convention (purple = personal/session best, green = gaining,
     yellow = losing), not an official palette. Yellow needs a
     separate, darker value for text/badge use since the fill color
     itself fails contrast on a light background.
     TODO(#5, deferred per explicit scope gate): whether/how this same
     convention gets applied to the real app's DeltaStripChart.jsx is
     an open question reported separately, not implemented here. */

     No @font-face / webfont <link> exists anywhere in this site — 'Inter' and

     system; otherwise every visitor already falls through to system-ui/Segoe UI/
     Roboto (sans) or ui-monospace/SF Mono/Consolas (mono).
     Cyrillic (Russian): those fallback system fonts have full Cyrillic coverage
     on their respective platforms (Segoe UI/Windows, San Francisco via system-ui/
     macOS, Roboto/Android & ChromeOS) — no additional fallback needed.
     CJK (Japanese, Simplified Chinese): none of the above stacks include CJK
     glyphs, so Noto Sans JP / Noto Sans SC are added explicitly below.
     Deferred, not solved here: per-locale line-height/letter-spacing tuning for
     CJK and Arabic (needs real content review, not guessed now) and CJK
     line-breaking rules (word-break/line-break behave differently for ja/zh and
     aren't addressed by this font-stack change alone). */
