      Starting from Version 20250305 you should normally not use this file name any more as those styles would be added for all build environments. Instead define a parameter _custom_css_ in your [platformio.ini](platformio.ini) for the environments you would like to add some styles for. This parameter accepts a list of file names (relative to the project root, separated by , or as multi line entry)

-     Starting from version 20251007 you can define a parameter "custom_script" in your [platformio.ini](platformio.ini).
-     This parameter can contain a list of file names (relative to the project root) that will be added as a [platformio extra script](https://docs.platformio.org/en/latest/scripting/index.html#scripting). The scripts will be loaded at the end of the main [extra_script](../../extra_script.py).
-     You can add code there that is specific for your build.

-     ```
-      # PlatformIO extra script for obp60task

-      pcbvers = "unknown"

- *
- * puff.c is a simple inflate written to be an unambiguous way to specify the
- * deflate format.  It is not written for speed but rather simplicity.  As a
- * side benefit, this code might actually be useful when small code is more
- * important than speed, such as bootstrap applications.  For typical deflate
- * data, zlib's inflate() is about four times as fast as puff().  zlib's
- * inflate compiles to around 20K on my machine, whereas puff.c compiles to
- * around 4K on my machine (a PowerPC using GNU cc).  If the faster decode()
- * function here is used, then puff() is only twice as slow as zlib's
- * inflate().
- *
- * All dynamically allocated memory comes from the stack.  The stack required
- * is less than 2K bytes.  This code is compatible with 16-bit int's and
- * assumes that long's are at least 32 bits.  puff.c uses the short data type,
- * assumed to be 16 bits, for arrays in order to conserve memory.  The code
- * works whether integers are stored big endian or little endian.
- *
- * In the comments below are "Format notes" that describe the inflate process
- * and document some of the less obvious aspects of the format.  This source
- * code is meant to supplement RFC 1951, which formally describes the deflate
- * format:

- * Decode literal/length and distance codes until an end-of-block code.
- *
- * Format notes:
- *
- * - Compressed data that is after the block type if fixed or after the code
- *   description if dynamic is a combination of literals and length/distance
- *   pairs terminated by and end-of-block code.  Literals are simply Huffman
- *   coded bytes.  A length/distance pair is a coded length followed by a
- *   coded distance to represent a string that occurs earlier in the
- *   uncompressed data that occurs again at the current location.
- *
- * - Literals, lengths, and the end-of-block code are combined into a single
- *   code of up to 286 symbols.  They are 256 literals (0..255), 29 length
- *   symbols (257..285), and the end-of-block symbol (256).
- *
- * - There are 256 possible lengths (3..258), and so 29 symbols are not enough
- *   to represent all of those.  Lengths 3..10 and 258 are in fact represented
- *   by just a length symbol.  Lengths 11..257 are represented as a symbol and
- *   some number of extra bits that are added as an integer to the base length
- *   of the length symbol.  The number of extra bits is determined by the base
- *   length symbol.  These are in the static arrays below, lens[] for the base
- *   lengths and lext[] for the corresponding number of extra bits.
- *
- * - The reason that 258 gets its own symbol is that the longest length is used
- *   often in highly redundant files.  Note that 258 can also be coded as the
- *   base value 227 plus the maximum extra value of 31.  While a good deflate
- *   should never do this, it is not an error, and should be decoded properly.
- *
- * - If a length is decoded, including its extra bits if any, then it is
- *   followed a distance code.  There are up to 30 distance symbols.  Again
- *   there are many more possible distances (1..32768), so extra bits are added
- *   to a base value represented by the symbol.  The distances 1..4 get their
- *   own symbol, but the rest require extra bits.  The base distances and
- *   corresponding number of extra bits are below in the static arrays dist[]
- *   and dext[].
- *
- * - Literal bytes are simply written to the output.  A length/distance pair is
- *   an instruction to copy previously uncompressed bytes to the output.  The
- *   copy is from distance bytes back in the output stream, copying for length
- *   bytes.
- *
- * - Distances pointing before the beginning of the output data are not
- *   permitted.
- *
- * - Overlapped copies, where the length is greater than the distance, are
- *   allowed and common.  For example, a distance of one and a length of 258
- *   simply copies the last byte 258 times.  A distance of four and a length of
- *   twelve copies the last four bytes three times.  A simple forward copy
- *   ignoring whether the length is greater than the distance or not implements
- *   this correctly.  You should not use memcpy() since its behavior is not
- *   defined for overlapped arrays.  You should not use memmove() or bcopy()
- *   since though their behavior -is- defined for overlapping arrays, it is
- *   defined to do the wrong thing in this case.

- *
- * - The literal/length code is complete, but has two symbols that are invalid

- *   code is nine bits.  Therefore the code must be constructed with those
- *   symbols, and the invalid symbols must be detected after decoding.
- *
- * - The fixed distance codes also have two invalid symbols that should result
- *   in an error if received.  Since all of the distance codes are the same
- *   length, this can be implemented as an incomplete code.  Then the invalid
- *   codes are detected while decoding.

- * Process a dynamic codes block.
- *
- * Format notes:
- *
- * - A dynamic block starts with a description of the literal/length and
- *   distance codes for that block.  New dynamic blocks allow the compressor to
- *   rapidly adapt to changing data with new codes optimized for that data.
- *
- * - The codes used by the deflate format are "canonical", which means that
- *   the actual bits of the codes are generated in an unambiguous way simply
- *   from the number of bits in each code.  Therefore the code descriptions
- *   are simply a list of code lengths for each symbol.
- *
- * - The code lengths are stored in order for the symbols, so lengths are
- *   provided for each of the literal/length symbols, and for each of the
- *   distance symbols.
- *
- * - If a symbol is not used in the block, this is represented by a zero as the
- *   code length.  This does not mean a zero-length code, but rather that no
- *   code should be created for this symbol.  There is no way in the deflate
- *   format to represent a zero-length code.
- *
- * - The maximum number of bits in a code is 15, so the possible lengths for
- *   any code are 1..15.
- *
- * - The fact that a length of zero is not permitted for a code has an
- *   interesting consequence.  Normally if only one symbol is used for a given
- *   code, then in fact that code could be represented with zero bits.  However
- *   in deflate, that code has to be at least one bit.  So for example, if
- *   only a single distance base symbol appears in a block, then it will be
- *   represented by a single code of length one, in particular one 0 bit.  This
- *   is an incomplete code, since if a 1 bit is received, it has no meaning,
- *   and should result in an error.  So incomplete distance codes of one symbol
- *   should be permitted, and the receipt of invalid codes should be handled.
- *
- * - It is also possible to have a single literal/length code, but that code
- *   must be the end-of-block code, since every dynamic block has one.  This
- *   is not the most efficient way to create an empty block (an empty fixed
- *   block is fewer bits), but it is allowed by the format.  So incomplete
- *   literal/length codes of one symbol should also be permitted.
- *
- * - If there are only literal codes and no lengths, then there are no distance
- *   codes.  This is represented by one distance code with zero bits.
- *
- * - The list of up to 286 length/literal lengths and up to 30 distance lengths
- *   are themselves compressed using Huffman codes and run-length encoding.  In
- *   the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
- *   that length, and the symbols 16, 17, and 18 are run-length instructions.
- *   Each of 16, 17, and 18 are followed by extra bits to define the length of
- *   the run.  16 copies the last length 3 to 6 times.  17 represents 3 to 10
- *   zero lengths, and 18 represents 11 to 138 zero lengths.  Unused symbols
- *   are common, hence the special coding for zero lengths.
- *
- * - The symbols for 0..18 are Huffman coded, and so that code must be
- *   described first.  This is simply a sequence of up to 19 three-bit values
- *   representing no code (0) or the code length for that symbol (1..7).
- *
- * - A dynamic block starts with three fixed-size counts from which is computed
- *   the number of literal/length code lengths, the number of distance code
- *   lengths, and the number of code length code lengths (ok, you come up with
- *   a better name!) in the code descriptions.  For the literal/length and
- *   distance codes, lengths after those provided are considered zero, i.e. no
- *   code.  The code length code lengths are received in a permuted order (see
- *   the order[] array below) to make a short code length code length list more
- *   likely.  As it turns out, very short and very long codes are less likely
- *   to be seen in a dynamic code description, hence what may appear initially
- *   to be a peculiar ordering.
- *
- * - Given the number of literal/length code lengths (nlen) and distance code
- *   lengths (ndist), then they are treated as one long list of nlen + ndist
- *   code lengths.  Therefore run-length coding can and often does cross the
- *   boundary between the two sets of lengths.
- *
- * - So to summarize, the code description at the start of a dynamic block is
- *   three counts for the number of code lengths for the literal/length codes,
- *   the distance codes, and the code length codes.  This is followed by the
- *   code length code lengths, three bits each.  This is used to construct the
- *   code length code which is used to read the remainder of the lengths.  Then
- *   the literal/length code lengths and distance lengths are read as a single
- *   set of lengths using the code length codes.  Codes are constructed from
- *   the resulting two sets of lengths, and then finally you can start
- *   decoding actual compressed data in the block.
- *
- * - For reference, a "typical" size for the code description in a dynamic
- *   block is around 80 bytes.
