document BT_RIO_PROTRUDE in the generated environ.ini

The button-protrusion dial shipped with no player-facing documentation -- it
lived only in the source comment and the KB, so a tester who found the buttons
too long (or wanted them longer) had no way to discover the knob.

Adds a block to the self-documenting default environ.ini, at the end of the
cockpit section beside the other display-shaping options (BT_MFD_SCALE,
BT_RADAR_SCALE, BT_RADAR_POS, BT_COCKPIT_TINT): what it does, that it is a
LONGER bar rather than a wider button (press target and imagery unchanged),
that it touches only the red MFD and yellow map buttons, the 10 default, 0 for
the original look, the 1-200 range, and the gotcha that it takes a NUMBER --
'on' parses to 0 and turns it off.

Verified by generating a fresh environ.ini from this build and reading the
block back as a player would see it.  The loader has no allowlist and refuses
only BT_JOYCONFIG, so the key applies from the file; a real env var still wins
over it, per the file's own contract.

NB the default is only written when environ.ini is ABSENT (and only beside
BTL4.RES), so existing installs keep their file and will not gain this text --
the handout/KB remain the channel for testers who already have one.

-**A FLASHING radar button goes RED — `BT_RADAR_FLASH_RED` (2026-08-14, player request)
-[T2 pixel-measured]. GLASS-ONLY DEVIATION (#154-class).** The radar's buttons are the yellow
-class, so an alerting lamp pulsed *yellow among yellows* — a brightness change only, and the
-night-16 miss that also produced the #172 ring and the protrusion bonus. The three desktop
-renderers now swap the **bright** colour of a **flashing** radar button to the house red
-(230,70,70 — the MFD family), so an alert reads as a *colour* change. Only the bright phase
-moves; dim/off keep the yellow family, so a non-alerting radar button is unchanged. One
-decode, `BTRadarLampBright(lampState)` in `L4VB16.h` beside `BTLampBrightnessOf`, consumed by
-all three renderers (`CkLampColors` in the surround, `PaintGlass` in the exploded windows,
-`L4PADPANEL`) so they cannot drift — the lesson of the L4RIOBANK geometry split. `=0` restores
-the yellow bright. The pod's own buttons are single-colour backlit hardware and cannot do this;
-the serial RIO lamp path is untouched, so this is desktop-only by construction.
-
-**Bench hook `BT_LAMPTEST=<addr>[,<state>]` (2026-08-14).** Forces ONE lamp's state at
-`PadRIO::GetLampState` — the single read point all three desktop renderers share — so lamp
-rendering can be checked without inducing the fault that would raise it (a generator trip, an
-ammo alarm). Default state `0x33` = the Panic lamp's alert shape (flashFast + state1Off +
-state2Bright, a hard dark/bright pulse); addresses and states take `0x` hex. This is how the
-red-flash change above was verified: `BT_LAMPTEST=0x1b` (GeneratorB's radar lamp, the night-16
-one) then a pixel tally of the radar window — **620 house-red px with the feature on, 0 with
-`BT_RADAR_FLASH_RED=0`**, and the yellow count falling by exactly that many (2820 → 2196).
+**Protrusion bonus — `BT_RIO_PROTRUDE` (2026-08-14, player request) [T2 receipt+screenshot].**
+Players asked for more of the RIO buttons to clear the glass so a FLASHING lamp is easier to
+notice. `BTRioBankMetricsFor` now adds a flat **+10px** to `strip` AFTER the scale, so the bar
+reaches that much further out on every renderer; `BT_RIO_PROTRUDE=<px>` tunes it (`0` restores
+the pre-2026-08-14 geometry). Deliberately FLAT, not scaled: the surround runs the glass at half
+scale where the strip sits on the 6px floor — a scaled bonus would help least exactly where the
+lamps are smallest — and that floor already trades proportionality for legibility. Because only
+`strip` moves, this touches exactly the **red MFD** and **yellow radar** buttons (+ the radar
+foot row) and grows them **outward only**: the layout anchors the inboard edge, so under-glass
+depth, button WIDTH and the press targets are unchanged. The **blue flight cells** are laid out
+from `cellW/cellH` and never see it (receipt: their bank bounds are byte-identical). Verified by
+`BT_RIOBANK_LOG` A/B — e.g. Heat MFD top button `y 21→11, h 126→136` with its bottom edge fixed
+at 147, bank bounds `252→272` tall, no negative coordinates — plus a surround screenshot pair.
+Relation to **#172**: the alert RING (`BT_ALERT_RING`, default off) answered the same night-16
+complaint after a *"+8px grown-face bloom"* was rejected on the bench as "the button got fat";
+this is a different shape — the lamp keeps its width and simply shows more of its own bar — so
+the ring stays optional. Desktop-glass affordance only; the pod's buttons are physical and
+backlit and never had this problem.
