* Shared EEPROM sizing for all Epomaker FS026 (ES32, Cortex-M0) keyboards.
*
* These boards emulate EEPROM inside two 8 KB internal-flash pages via the
* custom driver in user_eeprom.c. For the wear-levelling page transfer to
* work, every live 16-bit variable must fit inside a single page, which caps
* the usable space at roughly 4092 bytes.
*
* We provision enough for 8 VIA layers on the largest FS026 matrix
* (6x16 = 96 keys => 192 bytes/layer):
*
* dynamic keymap start (eeconfig + VIA config) : 46
* 8 layers * 192 bytes : 1536 -> ends at 1582
* macro region : ~400 bytes (up to MAX_ADDR)
*
* EEPROM_SIZE is kept at DYNAMIC_KEYMAP_EEPROM_MAX_ADDR + 65 on purpose: the
* driver reserves 64 "private" bytes (NB_OF_PRIVATE_VAR) and refuses to persist
* any variable whose index is >= EEPROM_SIZE, so this margin guarantees every
* keymap/macro byte is actually written to flash.
*
* Smaller boards (e.g. th40, 5x12 = 60 keys => 120 bytes/layer) simply use less
* of the same budget. To raise the ceiling for a future larger-matrix board,
* bump both values here (staying under ~4000) -- every FS026 board inherits it.
