mem_alloc_pages/mem_free_block/mem_get_page/mem_info, implemented twice:
mem_estex.c via ESTEX $3C-$3E (INFOMEM/GETMEM/FREEMEM), mem_bios.c via
the BIOS $C0/$C2-$C4/$C6 EMM_FN* calls. lib/Makefile already listed both
under LIBC_C.

palette.h/video/palette.c wrap BIOS $A4 PIC_SET_PAL/PIC_GET_PAL and $A6
SET_PAL_INIT for the 8 palette pages (0-3 graphics, 4-7 text planes).
gfx_palette.c and conio/text_palette.c are thin per-domain wrappers;
text_palette.c maps the text "plane" 0..3 (paper/ink/blink-paper/
blink-ink) onto BIOS pages 4..7. Covered by tests/text_palette.

_get_cursor/_set_cursor now use BIOS GetCursor/SetCursor (RST 8, 08Eh/084h)
instead of ESTEX CURSOR/LOCATE; cursor position packed into a two_bytes
union. get_videotextmode/set_videotextmode renamed to gettextmode/settextmode.

Direct __naked z80 wrappers over BIOS LP_PRINT_*/LP_SET_PLACE/LP_GET_PLACE
(RST 8, opcodes 081h-08Eh) for fast text rendering — a single BIOS call
replaces a wrchar() loop for constant-attribute/constant-character runs.
Covered by tests/bios_text.

- Split tests/ (libc feature tests) and examples/ (real apps); shared
app.mk in repo root, was examples/example.mk
- libc/io/* split into libc/{conio,env,errno,file,mouse,string,sys,
time,video}/ — clearer module boundaries
- New examples/mdview/: markdown viewer (Phases 1-5 + light nested
lists). Headers (H1-H4), HR, ulist/olist/quote with nesting via
leading spaces, fenced code blocks, inline emphasis (bold/italic/
underscore/code), wrap/unwrap mode with soft wrap (F2), horizontal
pan (← →) with '>' truncation indicator
- libc additions: scroll() in conio (ESTEX SCROLL), strlwr/strupr,
gets() test
- Makefile updates across tests/ for the new shared app.mk path

print_hex(uint8_t) was an early bare-metal helper doing exactly what
hex8() in the freshly-ported hex_print.c does (two-digit hex via
putchar()). hex8() is smaller (asm cp/sbc/daa nibble trick, no LUT)
and consistent with the dec8/hex16/dec16/hex32/dec32 family.
• Replaced print_hex() calls with hex8() in examples/banked and
examples/bankedbg.
• Removed libc/stdio/print_hex.c, dropped its prototype from
sprinter.h and its entry from lib/Makefile.

libc/mem/:
• Split bank_io.c into bank_io_w3.c (existing W3 helpers, base 0xC000,
port 0xE2) and bank_io_w1.c (new mirror through W1, base 0x4000,
port 0xA2). Two .rel files so DCE picks only the needed group:
a W3-only user pulls ~70 bytes instead of all 134. W1 variants are
`--memory tiny`-only (any other mode runs code from W1 or uses W1
for the banked-code segment, swapping it crashes).
• mem_alloc.c: add CF=err checks for mem_free_block and mem_get_page
(were silently ignored), per-function docstrings on alloc/free/
get_page/info, drop the confused "wait wrong order" comment in
mem_info. Header sprinter_mem.h gets matching per-function doc.
libc/stdio/:
• Add hex_print.c (hex8/hex16/hex32, ~26 bytes) and dec_print.c
(dec8/dec16/dec32, ~170 bytes) ported from solid-c STDLIB.ASM.
Replaces the printf("%u"/"%X") wrappers in solid_helpers.c that
dragged in the 3-5 KB printf machinery.
- hex* use the classic cp 10 / sbc 0x69 / daa nibble→ASCII trick;
hex8 self-calls for the high nibble, hex16/hex32 tail-call hex8.
- dec32 is the master routine; dec8/dec16 jump into shared entry
points (__dec_entry3 / __dec_entry5). 32-bit subtract-power-of-10
keeps the high 16 bits in HL alt (shadow set).
- DISCOVERY: ESTEX PUTCHAR ($5B) on our Sprinter build preserves
the main register set + IX but CLOBBERS the shadow set
(BC'/DE'/HL'). solid-c's original code assumed otherwise and
garbled output for values ≥ 6 digits. Fix: save/restore HL alt
around the RST 10 in _dec_emit_or_skip. Documented in
memory/estex_putchar_abi.md.
• file.c: drop stdaux/stdprn (no Sprinter printer API), change
stdin/stdout/stderr fd markers to 0/-1/-2 (positive fds clash with
ESTEX OPEN return values), add TODO header pointing at v2 buffered
FILE rewrite (see docs/TODO.md for the Solid-C reference struct).
bin/sprinter-cc:
• --memory big and --memory huge now always use crt0_banked.s (was:
only with --bank flags), matching docs/memory_modes_implemented.md.
When the user has no --bank flags, generate a tiny stub with
`const uint8_t n_banks = 0;` and assemble bank.s for _bank_pages.
Without this fix, openenv with --memory big could not see the
estex_file_handle symbol exported by crt0_banked.
examples/openenv:
• Add usage of estex_file_handle to confirm the crt0_banked startup-
info is reachable. Local extern decl — keeps the symbol out of
sprinter.h since it only exists in big/huge builds.
examples/dec_test:
• New regression test covering hex8/16/32 and dec8/16/32 across the
interesting boundary values.
.gitignore: add .kilo/ (editor session cache).
