Minor edit.

✅ Add
-o autotrim=on: Enables continuous TRIM support for SSDs, improving
long-term performance.

-O recordsize=128K: Ensures boot filesystem stays within GRUB's block
size limit (critical when using large_blocks).

🔁 Remove
    Individual -o feature@...=enabled lines: Since compatibility=grub2
automatically enables them, listing them is redundant.
