/* =========================================================================
   ISR Dashboard — "Editorial academic" theme (2026-07)
   Override layer loaded AFTER style.css. Retunes the design tokens (fonts,
   colours, radius) — most of the app is variable-driven, so this restyles
   nearly everything — and adds the new left-sidebar shell, stats band,
   table, form, status and card treatments from the design handoff.

   Palette: Balgrist blue #1D4F91 accent on a cool paper (#FAFBFC).
   Fonts:   Source Serif 4 (display) + Instrument Sans (UI/body).
   Reversible: remove the <link> in ui.php to fall back to style.css.
