Graphics: text_fonts (bitmap layout, styles), sprites (DMA, multiplexing), gfx_base (chipset detection), rastport (draw modes, clipping), ham_ehb (mermaid fixes), display_modes (HAM palettes)

Devices: scsi (per-model interfaces, Gayle limits, CD-ROM, native vs vendor drivers), console (ANSI sequences, CON:/RAW:), parallel (CIA registers, pinout), timer (resource exhaustion), gameport (quadrature, XOR state)

Libraries: workbench (WBStartup, AppWindow/Icon/MenuItem), rexxsyslib (ARexx port hosting, command parsing), diskfont (font directory, colour fonts), keymap (rawkey codes, dead keys), locale (catalogue system, date formatting), layers (ClipRect, refresh types), utility (TagItem chains), icon (DiskObject, ToolTypes), iffparse (IFF structure, ByteRun1), expansion (Zorro AutoConfig)

Networking: tcp_ip_stacks (major rewrite - Amiga vs Unix architecture, SANA-II pipeline, PPP/SLIP dial-up, Ethernet cards, MiSTer), bsdsocket (pure API ref), sana2 (buffer hooks, driver requirements), protocols (all code examples). Deduplicated overlap between the three files.

Toolchain: debugging (Enforcer patterns, SnoopDOS, GDB remote, kprintf checklist), sasc (pragma encoding, __saveds idioms), stormc (NEW - StormC IDE, C++, PowerPC)

References: error_codes (DOS, Exec, trackdisk, Intuition error tables)
Driver development: rtg_driver (Native driver analysis, P96 tuning)

All 22 README indexes updated. Root README synced with stormc.md entry.
