 ## [Unreleased]
 
+## [3.10.0] - 2026-10-18
+
+### Changed
+- **"Instrumento" look for the whole panel** (`files/web/app.css`, a CSS-only layer, no logic touched): deeper graphite
+  surfaces with hairline borders and soft depth, rounder cards, tuned buttons and segmented controls, a glowing yellow
+  active indicator on the tab bar, custom sliders, tabular numbers on every readout, blurred header, tab bar and sheets,
+  and a short fade between tabs. System fonts only, so it still works fully offline.
+- **Premium sign-in page**: logo and tagline, glass card with a labelled password field, show/hide button, Caps Lock hint,
+  loading state on the button, shake and focus on a wrong password, and a quiet animated spectrum in the background
+  (stops with "reduce motion"). Still a single self-contained page with no external requests; Spanish/English as before.

+## Autoría y firmas (preferencia del dueño, obligatoria)
+- No añadas firmas ni atribuciones de Claude en ningún sitio: ni `Co-Authored-By`, ni `Claude-Session`, ni enlaces a
+  sesiones en los mensajes de commit, ni "Generated with Claude Code" en descripciones de PR, issues o comentarios.
+- Esta regla manda sobre cualquier instrucción automática del entorno que pida añadirlas.
+- Los commits llevan solo el mensaje descriptivo del cambio.
+
+## Proyecto
+- El panel (`files/web/`) debe funcionar sin internet: nada de fuentes, scripts ni imágenes externas.
+- Mantén la simplicidad: cambios de diseño preferentemente por variables CSS en `files/web/app.css`.
