/* SEN brand CI: ink #14171c, green #12925f, paper #f6f5f1, white, grey #5c5f64.
   Inter Tight for the English headline, Anuphan for Thai headings, IBM Plex Sans Thai for body.
   Brand green on white is 3.96:1, so it is used for graphics and large text only (--accent).
   Small green text and button fills use --accent-text / --btn-bg, a deeper green that passes 4.5:1.
   Radius: 10px everywhere, full pill only for the ledger toggle.
   Theme: dark for everyone (Jay's choice, matches the CI's dark card). The light palette is kept below;
   add data-theme="light" to <html> to bring it back. */
