Selecting a variant from the Hold-Enter accent popup (e.g. 'o' -> 'o with
acute') correctly stored the real UTF-8 character in the text buffer, but
the live-typing preview line rendered it as the plain base letter -- the
accent was invisible even though the data was right.
Root cause: DisplayDriver::translateUTF8ToBlocks() transliterates extended
Latin characters down to ASCII for display drivers whose font can't render
them; real boards with the pixel-perfect MiscFixedFont override it to a
plain passthrough once _single_font is set (SH1106Display.cpp etc).
SimDisplayDriverCanvas reuses that same MiscFixedFont/MiscFixedRenderer
(confirmed the popup's own preview renders diacritics correctly, since it
prints its own variants directly rather than through this path) but never
added the matching override, so every string routed through
translateUTF8ToBlocks() -- not just the keyboard preview -- silently lost
its diacritics.

Two more real-vs-sim mismatches, found after seeing the rendered UI:
1. The Clock screen's big time display (setTextSize(2)) rendered at size 1
-- SimDisplayDriverCanvas ignored setTextSize() entirely (a leftover
no-op from the old system-font renderer) and never overrode
getCharWidth()/getLineHeight(), so the big-digit layout math in
UITask.cpp's drawBig() came out wrong even once print() itself gained
real font support. Track _text_sz, scale both metrics by it (matching
SSD1306Display's own getCharWidth()==6*_text_sz pattern), and pass it
through to miscFixedPrint() in target.cpp instead of a hardcoded 1.
2. The Home carousel's "<PRESS_LABEL> to open" hint said "long press to
open" -- true only for touchscreen-only boards with no dedicated Enter
button (PRESS_LABEL's #if UI_HAS_JOYSTICK / #else split in
examples/companion_radio/ui-new/UITask.cpp). The sim's D-pad + OK key
behaves like a joystick board (a SHORT Enter press opens each page;
holding it separately reaches the real context menu via
handleLongPress()), so showing the touchscreen wording was both
inaccurate and different from what a real joystick board like Heltec V3
displays. Added SIM_PLATFORM to that #if alongside UI_HAS_JOYSTICK --
UI_HAS_JOYSTICK itself stays unset, since its other two gates
(begin()-ing/polling real joystick MomentaryButton objects) need
hardware the sim's target.cpp doesn't declare.
Verified in real Chromium: Clock screen shows "08:11:10" at real double
size above the normal-size date line; Home carousel now says "press Enter
to open". Full regression clean: 3 native envs, wasm companion_radio, the
2-instance+repeater mesh demo, and the long-press context-menu test.

Two prototype polish fixes ahead of the website embed work:
1. Holding Enter (the sim's main way into "the rest of the options") did
nothing -- the JS bridge's sim_enqueue_key() went straight to
enqueueKey(), bypassing UITask::handleLongPress() entirely, so
KEY_CONTEXT_MENU could never be reached. Add injectSimKeyLongPress()/
sim_enqueue_key_longpress(), which does route through the real
handleLongPress() (same code a real MomentaryButton(pin, 1000, ...)
reaches), and wire up press-and-hold (buttons + Enter/Space key) in both
web harnesses with the same 1000ms threshold real hardware uses.
2. SimDisplayDriverCanvas::print() drew text with the browser's own system
font (ctx.fillText, '8px monospace') instead of the real bitmap font a
MeshCore-Solo board renders with OLED_MISC_FIXED_FONT=1 (see
solo/heltec_v3/platformio.ini). Vendor the real Adafruit_GFX (unmodified,
from the same PlatformIO registry package a real board build pulls) into
variants/sim/thirdparty/gfx/, and render print() through the real,
shared src/helpers/ui/MiscFixedRenderer.h + MiscFixedFont.h -- byte-
identical glyphs to real hardware, not a look-alike.
Verified in a real Chromium (Playwright): short Enter -> "CLOCK TOOLS",
held Enter -> "CLOCK FIELDS" (gotoDashboardConfig(), proving
KEY_CONTEXT_MENU is really reached); font renders as hard square pixels,
inverse/selected-row text still punches correctly through a filled bar.
Full regression re-run clean: all 3 native envs, wasm companion_radio, and
the two-instance + repeater mesh demo (relay routing, DM delivery).

Ports examples/simple_repeater to variants/sim/ (new sim_simple_repeater
native env + build_wasm_repeater.sh) and adds a JS "ether"
(variants/sim/web/mesh.html) that bridges two real companion_radio WASM
instances through a real simple_repeater instance in a strict A<->R<->B
topology (no direct A-B link), proving genuine relay routing rather than
a shortcut.
Also fixes multi-instance issues Phase 2's single-instance design never
surfaced: SimDisplayDriver's canvas context/id caching was keyed on a
single global instead of per-instance, and both wasm builds were missing
_malloc/_free/HEAPU8 runtime exports needed for the ether to poke bytes
into an instance's memory.

New board variant compiling the unmodified MyMesh/UITask/DataStore app
logic against real mesh::Radio/MainBoard/RTCClock/RNG interfaces, for
running the actual firmware outside embedded hardware:
- Native (plain g++, platform = native): ASCII-art display over stdout,
stdin-driven input, local-disk-backed DataStore/IdentityStore.
- Emscripten/WASM (variants/sim/build_wasm.sh, since PlatformIO's native
platform force-overrides any CC/CXX toolchain override back to system
clang++): canvas-backed display, IDBFS-backed persistence across page
reloads, JS-callable input via sim_enqueue_key(), emscripten_set_main_loop.
Real rweather/Crypto (AES128/SHA256/Ed25519) vendored unmodified and
proven working on both targets. variants/sim/web/index.html is a bare
verification harness, not the polished website embed.
