+    E-Ink display driver adapter
+        - ED047TC1 (via FastEPD library)
+        - Manufacturer: E Ink / used in LilyGo T5-E-Paper-S3-Pro
+        - Size: 4.7 inch
+        - Physical resolution: 960px x 540px
+        - Interface: 8-bit parallel (NOT SPI)
+
+    Unlike the other NicheGraphics EInk drivers, this one drives a parallel e-paper
+    panel via the FastEPD library. SPI parameters passed to begin() are ignored.
+
+    The ED047TC1 panel has an inactive pixel border on all four edges (~4–8 physical
+    pixels). DISPLAY_WIDTH / DISPLAY_HEIGHT expose a reduced "safe area" to InkHUD so
+    that content is never drawn into this dead zone. The update() method copies the
+    InkHUD frame buffer into the centre of the larger physical 960×540 buffer, using
+    H_OFFSET_BYTES (horizontal, whole bytes = 8 pixels per byte),
+    V_OFFSET_TOP and V_OFFSET_BOTTOM (vertical, pixel rows) to position it.
+
+    Changing these constants shifts content inward from each physical edge:
+        H_OFFSET_BYTES = 1  →  8px left margin, 8px right margin   (960 – 8 – 8   = 944)
+        V_OFFSET_TOP   = 9  →  9px top margin  (asymmetric: top ≠ bottom)
+        V_OFFSET_BOTTOM = 8 →  8px bottom margin                    (540 – 9 – 8   = 523)
